I want to install PostgreSQL 11 on an EC2 instance, based on the Amazon Linux AMI 2 image. Following posts, SO questions, and finding the latest Postgresl yum repository, I tried:
sudo yum install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
I get this error:
--> Processing Dependency: /etc/redhat-release for package: pgdg-redhat-repo-42.0-4.noarch
--> Finished Dependency Resolution
Error: Package: pgdg-redhat-repo-42.0-4.noarch (/pgdg-centos11-11-2.noarch)
Requires: /etc/redhat-release
I'm stuck.. is there a clean way to overcome this problem?
Aman,
It may help you: https://stackoverflow.com/a/55883490/7541412
Moreover, if you think PostgreSQL v10 can resolve your issues. You can try these commands:
sudo yum update -y
sudo amazon-linux-extras enable postgresql10
After having PostgreSQL in your repository, now you can install:
yum clean metadata
yum install postgresql
Thanks!
I successfully installed 11.5 on Amazon Linux using
sudo amazon-linux-extras install postgresql11
I had issues with the Amazon Linux 2 AMI for CodeBuild using Python 3 but amazon-linux-extras only using Python 2 (totally bizarre considering Python 2 has been sunset, I know). From this thread you can copy the amazon_linux_extras from the Python 2 site-packages to the Python 3 one.
To find the location of amazon-linux-extras use
find -type d -name "amazon_linux_extras" # note the underscore (_), not dash (-)
To find the Python 3 site-packages directory
find -type d -name "site-packages"
To copy across
cp -r /path/to/amazon_linux_extras /path/to/python3/site-packages
Once I had done that, I used #Hassan's answer to upgrade to PostgreSQL 11.
You can install PostgreSQL by running the following command:
$ sudo yum install postgresql postgresql-server postgresql-devel postgresql-contrib postgresql-docs
Out of curiosity why are you not using PostgreSQL on AWS RDS?

i installed postgres on a new vps and then i installed postgis, but trying to create a postgis extension i always get this error:
create extension postgis;
ERROR: could not load library "/usr/lib/postgresql/10/lib/rtpostgis-2.4.so": /usr/lib/x86_64-linux-gnu/libssl.so.1.1: version `OPENSSL_1_1_1' not found (required by /usr/lib/x86_64-linux-gnu/libmysqlclient.so.20)
i have no idea how to solve it.
i also tried to install openssl and libssl-dev but didn't help
edit:
i am using 18.04.4 LTS ubuntu
i install issuing:
sudo apt install postgresql postgresql-contrib
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get update
sudo apt-get install postgis
Issue with Ubuntu 18.04
For missing OpenSSL 1.1.1 on Ubuntu 18.04 take a look at this answer. You might need to download the .deb file and install it manually.
PostgreSQL 10 and PostGIS 2.4
In this article a similar error is solved by creating a symbolic link to the rtpostgis library available in the system, so that you can trick PostGIS 2.4 into thinking that the file exists, e.g. rtpostgis-2.5.so to rtpostgis-2.4.so:
$ ln -s rtpostgis-2.4.so rtpostgis-2.5.so
PostgreSQL 10 and PostGIS 3
To install PostGIS 3 (newer version) in a PostgreSQL 10 environment try:
sudo apt-get install postgresql-10-postgis-3
After that you will have the required libraries to perform CREATE EXTENSION postgis.
I am attempting to install the latest PostGIS 3.0.x on CentOS 8, with no luck.
I don't think anyone is running PostGIS on RHEL 8 or CentOS 8, I can't understand why not. It does not seem possible to install.
I have successfully installed Postgres 12.0 by disabling the RHEL AppStream
Steps I took installing postgres 12 on CentOS 8:
1)
#dnf install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
2)
#dnf --disablerepo AppStream install postgresql12
#dnf --disablerepo AppStream install postgresql12-server
I am attempting now to install PostGIS.
#dnf list --available | grep postgis30
I see that postgis30_96 is the latest offered (as listed below):
postgis30_96.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-client.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-client-debuginfo.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-debuginfo.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-devel.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-docs.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-gui.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-gui-debuginfo.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-utils.x86_64 3.0.0alpha4-6.rhel8 pgdg96
When I try to install with the following command:
#dnf install postgis30_96
I get these errors:
Last metadata expiration check: 1:22:58 ago on Tue 15 Oct 2019 08:25:10 PM UTC.
Error:
Problem: cannot install the best candidate for the job
- nothing provides hdf5 needed by postgis30_96-3.0.0alpha4-6.rhel8.x86_64
- nothing provides xerces-c needed by postgis30_96-3.0.0alpha4-6.rhel8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
I look for xerces-c, and nothing is returned:
#dnf list --available | grep xerces-c
Where do I get xerces-c to install?
I look to see if hdf5 is available to install (dependency)
#dnf list --available | grep hdf5
and nothing is returned. How do I satisfy these dependencies, so that PostGIS will install?
I goto the hdf5 website, download the source and it's a BIG FAT MESS. The build/install instructions do not work - the code is out of sync with the install instructions.
I check the hdf5 website and find another set of build/install instructions, and they too are out of sync with the latest code base. I don't know which way is up with this project, if it's a zombie project out there on the web, seemingly alive, but nobody's home.
How do I get hdf5 easily onto my system and xerces-c so that nothing existing gets mucked up? I would prefer to install these through any somewhat sanctioned CentOS 8 package repo using dnf.
I can't log this issue on the PostGIS ticket tracking system. Logging a ticket there requires an OSGEO ID, and when I request a 'mantra' to get started, nothing is returned, no response,
OSGEO is yet another zombie project, nobody's home. https://www.osgeo.org/community/getting-started-osgeo/osgeo_userid/
Please respond only if you have actually done this yourself on a CentOS 8 machine or VM, while I appreciate suggestions, pointers or imaginations from others, it pollutes r/postgis reddit with misinformation, non-working solutions, and not only wastes my time with dead ends, but also the time of others.
Someone else inevitably comes along with the same problems and is misguided with these those that are well-intentioned, but provide incorrect or incomplete information.
I had the same problem and finally found the solution. I need postgis25 for postgresql10, so I typed this command
dnf --enablerepo=PowerTools install postgis25_10
The PowerTools repo has the packages from codeready-developer repo, from Redhat CodeReady Studio. It contains a lot of useful tools.
Cannot enable PowerTools for RHEL 8
https://access.redhat.com/discussions/5417621
Remarks: PowerTools is a CentOS repository. On RHEL 8 we have the CodeReady Builder repository!
I am now able to install PostGIS-3 for PostgreSQL-12 on RHEL-8.
Solution:
sudo subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms
dnf install postgis30_12
Summing up the previous answers, these are the commands needed to install PostGIS-3 on CentOS-8:
dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
dnf -qy module disable postgresql
yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
dnf --enablerepo=PowerTools install postgresql12-server postgresql12-contrib postgis30_12
Many of the answers were helpful. To sum up the steps I had to take and errors in the instructions at https://people.planetpostgresql.org/devrim/index.php?/archives/107-Installing-PostGIS-3.1-and-PostgreSQL-13-on-CentOS-8.html
As mentioned by Marcelo, for RHEL use code-ready, not powertools.
As mentioned in this thread, don't mix packages. Run dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
to get the pgdg repo before installing postgres. Then run dnf -qy module disable postgresql if needed then install postgres like sudo dnf install -y postgresql13-server
The command to install epel-repo listed here may not work. Try sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
Get the name of the latest postgis release with this command. sudo dnf list --available | grep postgis3 As mentioned by Nick, the second two digits are your postgres version.
Install postgis sudo dnf -y install postgis3x_xx I repeat, the second two digits are your postgres version.
So, in summary, to install postgres and postgis on my rhel8 sytstem, I ran these commands in this order.
sudo dnf -qy module disable postgresql
sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
sudo dnf install -y postgresql13-server
sudo /usr/pgsql-13/bin/postgresql-13-setup initdb
sudo systemctl enable postgresql-13
sudo systemctl start postgresql-13
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms
sudo dnf -y install postgis31_13
The postgis30_96 packages are for Postgres 9.6. You need postgis30_12 for Postgres 12.
These packages are definitely in the repo, so if your dnf list isn't seeing them, it may be an instance of a known issue in which "yum/dnf refuse to find/install many packages from PGDG repository on RHEL8".
As a workaround, the Postgres Yum Howto recommends this installation procedure:
dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
dnf -qy module disable postgresql
dnf install postgresql11-server postgresql11-contrib
Percona Postgresql 13 And Postgis 3.0
https://www.percona.com/doc/percona-repo-config/index.html
dnf remove postgresql
sudo dnf install https://repo.percona.com/yum/percona-release-latest.noarch.rpm
sudo percona-release setup ppg-13
You can refer here:
https://www.percona.com/doc/postgresql/LATEST/installing.html#using-the-rpm-format
sudo dnf module disable postgresql
sudo dnf install percona-postgresql13-server
sudo dnf install percona-pg_repack13
sudo dnf install percona-pgaudit
sudo dnf install percona-pgbackrest
sudo dnf install percona-patroni
sudo dnf install percona-pg-stat-monitor13
sudo dnf install percona-postgresql13-contrib
/usr/pgsql-13/bin/postgresql-13-setup initdb
sudo systemctl start postgresql-13
PostGIS
dnf -y config-manager --set-enabled PowerTools
dnf install -y postgis30_13 postgis30_13-client
What helped me in CentOS container (as a root):
yum -y install dnf-plugins-core && yum config-manager --set-enabled powertools
Installing dnf-plugins-core and enabling powertools.
I have successfully launched new AWS RDS PostgreSQL v10 instance and need to install PostgreSQL v10 client on Amazon Linux EC2 instance.
I have tried to install it with yum, but it cant find the package for v10:
[ec2-user#ip-X-X-X-X ~]$ sudo yum install -y postgresql10
Loaded plugins: priorities, update-motd, upgrade-helper
amzn-main | 2.1 kB 00:00:00
amzn-updates | 2.5 kB 00:00:00
No package postgresql110 available.
Error: Nothing to do
Previously I managed to install PostgreSQL client v9.5 with:
[ec2-user#ip-X-X-X-X ~]$ sudo yum install -y postgresql95
I guess I need to add Postgres yum repository, as mentioned in https://www.postgresql.org/download/linux/redhat/. But what Platform should I choose for Amazon Linux? Red Hat?
You can try to run the following command on your Linux server:
sudo amazon-linux-extras install postgresql10
Packages/Repos which is designed to work of RedHat will work on Amazon Linux also, Amazon Linux is a minimal-install version of RHEL. You may run into compatibility issues if you select old version of Amazon Linux (Amazon linux 1) for the below steps, otherwise it should work fine in the latest version Amazon Linux 2.
Check Amazon Linux version
[ec2-user ~]$ cat /etc/system-release
Amazon Linux release 2.0 (2017.12) LTS Release Candidate
Install RHEL 7 yum repo for PostgreSQL
[ec2-user ~]$ sudo yum install -y https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-7-x86_64/pgdg-redhat10-10-2.noarch.rpm
[ec2-user ~]$ sudo sed -i "s/rhel-\$releasever-\$basearch/rhel-latest-x86_64/g" "/etc/yum.repos.d/pgdg-10-redhat.repo"
Install PostgreSQL Client v10
[ec2-user ~]$ sudo yum install -y postgresql10
[ec2-user ~]$ psql --version
psql (PostgreSQL) 10.3
Read more about Amazon Linux 2
Note! Amazon Linux 2 provides additional package installation through Amazon Linux Extras Repository (amazon-linux-extras) ((client only)). Since postgresql10 is not yet available, adding extra yum repo is the only solution per today.
UDATE 2019May
those who see
Error: Package: pgdg-redhat-repo-42.0-4.noarch
(/pgdg-redhat-repo-latest.noarch)
Requires: /etc/redhat-release
may still install step by step all dependencies and the server with:
yum install -y https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-latest-x86_64/postgresql10-libs-10.7-2PGDG.rhel7.x86_64.rpm
yum install -y https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-latest-x86_64/postgresql10-10.7-2PGDG.rhel7.x86_64.rpm
yum install -y https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-latest-x86_64/postgresql10-server-10.7-2PGDG.rhel7.x86_64.rpm
Since none of the previous answers worked for me, I'm adding a solution that let me install the postgresql10 client. We're using VERSION="2018.03" of Amazon Linux AMI in our pipelines.
Building from source:
Note: The link below points to postgresql 10.4, you may want to check for newer subversions
sudo yum install -y gcc readline-devel zlib-devel
wget https://ftp.postgresql.org/pub/source/v10.4/postgresql-10.4.tar.gz
tar -xf postgresql-10.4.tar.gz
cd postgresql-10.4
./configure
make -C src/bin
sudo make -C src/bin install
make -C src/include
sudo make -C src/include install
make -C src/interfaces
sudo make -C src/interfaces install
make -C doc
sudo make -C doc install
The new package should be installed with all its executables in here: /usr/local/pgsql/bin
Now, keep in mind that commands psql, pg_dump etc. still point to the old version of the psql client. You can run with the full executable paths (/usr/local/pgsql/bin/psql) or prepend the new directory at the beginning of your $PATH so that the system will look it up first:
Edit ~/.bash_profile adding this at the end:
export PATH="/usr/local/pgsql/bin:$PATH"
Then run:
source ~/.bash_profile
Now everything should be ready:
[ec2-user#ip-xx-x-x-xxx ~]$ psql --version
psql (PostgreSQL) 10.4
Adapting Haneef Mohammed's answer for Amazon Linux 1 (tested on 2018.03):
Go to the Postgres repositories page and grab the URL for 'Red Hat Enterprise Linux 6 - x86_64'. Install the PG repos and amend the entries, replacing '$releasever' with '6.9' (or newer?):
[ec2-user ~]$ sudo yum install -y https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-6-x86_64/pgdg-redhat10-10-2.noarch.rpm
[ec2-user ~]$ sudo sed -i "s/rhel-\$releasever-\$basearch/rhel-6.9-x86_64/g" "/etc/yum.repos.d/pgdg-10-redhat.repo"
Second part is the same:
[ec2-user ~]$ sudo yum install -y postgresql10
[ec2-user ~]$ psql --version
psql (PostgreSQL) 10.3
PGDG repo is no longer available for Amazon Linux. So you can use amazon repo.
amazon-linux-extras install postgresql10 vim epel -y
Or follow this article
https://installvirtual.com/install-postgresql-10-on-amazon-ec2/
As of May 25th, 2019, the following direct RPM installation worked for me on Amazon Linux 1 2018.03 (latest Beanstalk platform version) to install PostgreSQL Client 10.7:
sudo rpm -ivh --force https://yum.postgresql.org/testing/10/redhat/rhel-6-x86_64/postgresql10-libs-10.7-2PGDG.rhel6.x86_64.rpm
sudo rpm -ivh --force https://yum.postgresql.org/testing/10/redhat/rhel-6-x86_64/postgresql10-10.7-2PGDG.rhel6.x86_64.rpm
PSql10.7 installation (08/20/2019)
Remove all of the older version Psql client and perform the below steps:
wget https://yum.postgresql.org/10/redhat/rhel-6.9-x86_64/postgresql10-libs-10.7-1PGDG.rhel6.x86_64.rpm
wget https://yum.postgresql.org/10/redhat/rhel-6.9-x86_64/postgresql10-10.7-1PGDG.rhel6.x86_64.rpm
sudo rpm -ivh postgresql10-libs-10.7-1PGDG.rhel6.x86_64.rpm
sudo rpm -ivh postgresql10-10.7-1PGDG.rhel6.x86_64.rpm
This my 2019 solution:
Just do
sudo amazon-linux-extras install postgresql9.6
You should not have to download it from any outside source, since it is already given to you by default from Amazon, all you have to do is install it.
The other solutions didnt work for me and I spent a good amount time banging my head against the wall trying to figure out why.
And surprisingly even though you install psql9.6 you get version 10.
The following works for psql v11 on Amazon Linux (v1)
wget https://yum.postgresql.org/11/redhat/rhel-6.9-x86_64/postgresql11-libs-11.8-1PGDG.rhel6.x86_64.rpm
wget https://yum.postgresql.org/11/redhat/rhel-6.9-x86_64/postgresql11-11.8-1PGDG.rhel6.x86_64.rpm
sudo yum clean all
sudo rpm -ivh postgresql11-libs-11.8-1PGDG.rhel6.x86_64.rpm
sudo rpm -ivh postgresql11-11.8-1PGDG.rhel6.x86_64.rpm
The way I resolved the issue was by running
yum clean all
before
yum install -y postgresql10
on Amazon Linux
for v11 on Amazon Linux 2 I had to do
yum -y install https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-7-x86_64/pgdg-centos11-11-2.noarch.rpm
sed -i "s/rhel-\$releasever-\$basearch/rhel-7-x86_64/g" "/etc/yum.repos.d/pgdg-11-centos.repo"
I am in the process of installing PostGis over psql on a Debian machine (actually crunchbang).
I have completed the following steps:
$ wget http://download.osgeo.org/postgis/source/postgis-2.0.3.tar.gz
$ tar xzf postgis-2.0.3.tar.gz
$ cd postgis-2.0.3
$ ./configure
On the final step I get the following error:
configure: error: the PGXS Makefile /usr/lib/postgresql/9.1/lib/pgxs/src/makefiles/pgxs.mk cannot be found. Please install the PostgreSQL server development packages and re-run configure.
The issue is that I do already have Postgres installed:
$ psql --version
psql (9.1.9)
I have checked this on two machines with the same configuration and get the same error. What am I missing here?
PostgreSQL is broken down into several packages, and having psql installed doesn't imply that the development packages are also installed.
According to the error message:
Please install the PostgreSQL server development packages and re-run
configure
you need:
# apt-get install postgresql-server-dev-9.1
Also note there's a APT pgdg repository providing recent pre-compiled versions of postgres-related packages (including postgis) that you may use instead of self-compiling.
If your system is set up to use this repository, just do:
# apt-get install postgresql-9.1-postgis-2.0
Daniel's answer works great except that it needs the following update:
$ sudo apt-get install postgresql-9.1-postgis-2.1
These packages can be updated some time in future again. So, it is recommended to search for new packages using aptitude and install the appropriate one:
$ aptitude search postgis
Is it possible to install psycopg2 into a virtualenv when PostgreSQL isn't installed on my development system—MacBook Pro with OS X 10.6?
When I run pip install psycopg2 from within my virtualenv, I received the error shown below.
I'm trying to connect to a legacy database on a server using Django, and I'd prefer not to install PostgreSQL on my development system if possible.
Why not install PostgreSQL?
I received an error when installing PostgreSQL using homebrew. I have Xcode4—and only Xcode4—installed on my MacBook Pro and am thinking it's related to missing gcc 4.0. However, this is a problem for another StackOverflow question.
Update 8:37 AM on April 12, 2011: I'd still like to know if this is possible without installing PostgreSQL on my MacBook Pro. However, I ran brew update and forced a reinstallation of ossp-uuid with brew install --force ossp-uuid and now brew install postgresql works. With PostgreSQL successfully installed, I was able to pip install psycopg2 from within my virtualenv.

Preliminary Research
Below are the articles I read as preliminary research:
Installing psycopg2 to use Django with PostgreSQL on OS X
Installing psycopg2 on OS X
Using psycopg2 with virtualenv on Ubuntu JauntyLucid
Postgres, psycopg2, virtualenv install hints
apt-get install libpq-dev
helped me on debian squeeze
From comments:
apt-get install python-dev-is-python3
psycopg depends on pg_config command, and if you don't have it, you can't install psycopg.
If system installation is a problem to you, why don't you try compiling PostgreSQL and including generated bin files in your $PATH? Like:
export PATH=/path/to/compiled/postgresql/bin:"$PATH"
pip install psycopg2
brew install postgresql
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
pip3 install psycopg2
apt-get install libpq-dev
helped me in debian squeeze too . After that do pip install psycopg2. I faced problem of pg_config not found problem when i was setting up my environment on heroku , now its working fine .
You need to install the python-dev package in order to make use of python extensions such as psycopg2. I don't know how to install packages in mac but I run the following commands to install a python package on my Ubuntu machine.
sudo apt-get install python-dev
Or
sudo apt-get install python3-dev
if you are using Python3.x.
Once the installation is finished run the following command within your virtual environment.
pip install psycopg2
You don't need the complete PostgreSQL installed: you only need the client side libraries.
I solved it in MAC OSX using :
$ wget https://ftp.postgresql.org/pub/source/v9.5.3/postgresql-9.5.3.tar.bz2
$ tar xfv postgresql-9.5.3.tar.bz2
$ cd postgresql-9.5.3
$ ./configure
$ make
$ cd src/bin/pg_config
$ export PATH=`pwd`:"$PATH"
$ pip install psycopg2
Use pip install psycopg2-binary, it worked for me when pip install psycopg2 wasn't working.
Using the method you described in your April 12th update, I was able to install PostgreSQL(+1). Note that I originally was running Python 2.7.1 (32bit) and homebrew threw several errors and warnings regarding using a 32bit version of Python. I have since switched the 64/32 bit version of 2.7.1 and it works like a champ.
Regarding the pyscopg2, I was able to install it into my virtual environment from source by editing setup.cfg. I set pg_config to correct path inside homebrew's Cellar (pg_config=/usr/local/Cellar/postgresql/9.0.4/bin/pg_config). After saving the changes, I ran python setup.py install with zero issues. It's worth noting that I did not set the Mac's default python setting to 32 bit. I used the new 64 bit from start to finish.
After looking over some of the documentation, I think if I added homebrew's postgresql path to the system path I could have used pip to install it.

Update 6-8-2011:
While porting a project written on OS X to Windows 7, I found out that I had to install PostgreSQL on Windows as well. This ended up creating another user on my start up screen and other things that I just didn't like. While doing some digging I found Windows drivers for PostgreSQL here. I have since uninstalled the full PostgreSQL and installed the ODBC drivers which, thus far, work great.
To address the original question, after doing a bit more digging I think I found the equivalent ODBC for OS X here. I have not had a chance to try them out, but the concept works very well on Windows 7. I will update this when I get a chance to try them out. Until then, I hope this helps.
All from the above doesn't work for me (OS Catalina 10.15.1)
There was a conflict with classical postgres and homebrew version.
Please delete homebrew version by command
$ brew uninstall postgresql
and then install it from the official website:
$ sudo mkdir -p /etc/paths.d && echo /Applications/Postgres.app/Contents/Versions/latest/bin | sudo tee /etc/paths.d/postgresapp
It is actual for a simple psycopg2 install or django-heroku package.
if you have recently updated python or changed default python (let's say from 3.6 to 3.8). The following code
sudo apt-get install python-dev OR sudo apt-get install python3-dev
will be installing/working for the previous python version.
so if you want this command to work for the recently updated/changed python version try mentioning that specific version like python3.8 in command like
sudo apt-get install python3.8-dev
try above with following
pip install wheel
export PATH=/path/to/compiled/postgresql/bin:"$PATH"
sudo apt-get install libpq-dev
sudo apt-get install python3.x-dev **Change x with your version, eg python3.8**
pip install psycopg2-binary
pip install psycopg2
As I never needed to install postgresql database on this server I installed the following libraries on Ubuntu 14_04 version before running pip install psycopg2 on the same server
apt-get install libpq-dev python-dev
and then executed pip install psycopg2 within virtual env.
Output

I know you are asking for development environment but if you are deploying on server say, Heroku.
Just add below line in the requirements.txt of your project.
django-heroku==0.3.1
As this package itself will install the required packages like psycopg2 on server deployment.
Try to specify the version and it'll works, do it inside the venv
pip install psycopg2-binary==2.8.6
based on my experience, apt install libpq-dev then try to install psycopg2 inside venv will fix many issues, however for more information you can refer to this link:
