I am unable to install pg_config as an executable
You need to install postgresql-devel package.
Or build Postgres from source and then you'll have pg_config not from a package.
For AWS linux (or RedHat for that matter) use:
sudo yum install postgresql-devel
The above answer is correct: you need to install the -devel package. Furthermore, I found via this comment that you then might need to manually specify where to look for pg_config to build psycopg2.
In particular, I wound up running
python2.7 setup.py build_ext --pg-config /usr/pgsql-9.3/bin/pg_config install
Note that this path will depend on your postgres version.

I need your help with installation psycopg2 on MAC.
I've already installed:
Python 3.7.3 as a part of Anaconda environment
Postgres.app from https://postgresapp.com
When I'm trying to install psycopg2 package a terminal show me an error
Error: pg_config executable not found.
pg_config is required to build psycopg2 from source. Please add the directory
containing pg_config to the $PATH or specify the full executable path with the
option:
python setup.py build_ext --pg-config /path/to/pg_config build ...
or with the pg_config option in 'setup.cfg'.
I've read a number of articles where they recommend to provide $PATH before installing psycopg2, but the problem is in a fact that Postgres.app doesn't create the pg_config directory:
/Users/konstantin_klychkov/Library/Application Support/Postgres/var-12
the problem is in a fact that Postgres.app doesn't create pg_config directory:

I think you may be looking in the wrong place. pg_config is not a directory, but a program. Try putting /Applications/Postgres.app/Contents/Versions/12/bin in your $PATH:
$ ls /Applications/Postgres.app/Contents/Versions/12/bin | grep pg_config

Working on POC with netCDF(.nc) files. Would like do some visualisation and while trying to install Basemap having some issues.
As per the pre-requisites, got numpy and matplotlib installed.
geos is already installed

Depending on your runtime version you may be pointing at the wrong version of python (I'm assuming python 3) with your pip commands. Also, if you're installing python packages through pip inside of a notebook environment you're going to have a bad time. The best way to install through pip on a cluster is to use an init script.
There are errors when I try to install psycopg2
pip install psycopg2
I don't know whether I have pg_config or not. I tried these to find out where is pg_config, psql. but I don't understand how pg_config is not in the system when I have installed PostgreSQL(11.4). And if it is there in the system how to set the PATH so that psycopg2 installation is possible.

This worked for me
sudo yum install python-devel postgresql-devel rpm-build
pip install psycopg2
As per suggested by one of the users, I used these commands and it worked for me.
sudo dnf install python-devel postgresql-devel rpm-build
pip install psycopg2
OP put this as a comment. It also worked for me. It would be best if you added this as an answer.

Here is a list of packages I had to install for CKAN 2.7.0
python-setuptools-36.2.4-4.mga7.noarch.rpm
pgdg-redhat96-9.6-3.noarch.rpm
xml-commons git subversion mercurial postgresql96-server postgresql96-devel postgresql96 python-devel libxslt libxslt-devel libxml2 libxml2-devel python-virtualenv gcc gcc-c++ make java-1.6.0-openjdk redis tomcat tomcat-webapps tomcat-admin-webapps xalan-j2unzip policycoreutils-python mod_wsgi httpd tcl-devel redis
after installing these tools i was able to download the git successfully using
pip install --ignore-installed -e git+https://github.com/okfn/ckan.git#ckan-2.7.0#egg=ckan
I then added pgsql-9.6 to the path in order for ckan to recognize pg_config
PATH=$PATH:/usr/pgsql-9.6/bin
Now when I attempt to run the requirements.txt installation it fails with this error
ImportError: No module named pytz

If anybody can explain what the error means and what I need to install/modify I would greatly appreciate it. Seems there is a package called pytz missing but I cannot find information about it.
Thanks
pytz must must installed inside the virtualenv and the pip-requirements-docs.txt must be run prior to running requirements.txt.
First of all, I am sorry for asking a question that was asked million times, however, I couldn't resolve my issue.
TL;DR:
psycopg2 builds in Python3.4 virtualenv, but not in Python3.2; suspected dev packages missing, where can I get dev packages for old python releases?
Long story:
I should be writing code for Python3.2 using django with PostgreSQL database engine.
Ubuntu 15.04 by default ships with Python3.4 so I have build Python3.2 from source:
$ python3.2 --version
Python 3.2.6
virtualenv is created so:
myproject $ virtualenv -p python3.2 venv
New python executable in venv/bin/python3.2
Also creating executable in venv/bin/python
Installing setuptools, pip...done.
Installing requirements:
myproject $ source venv/bin/activate
(venv)myproject $ pip install psycopg2
The output log can be found in pastebin.
What I have read there:
GCC finishes whatever its doing without error messages; last non-error reporting line is
running install_lib
then it fails with
Command /home/julka/LP/myproject/venv/bin/python3.2 -c "import setuptools, tokenize;__file__='/tmp/pip-build-cbu7a3/psycopg2/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-cyu65o-record/install-record.txt --single-version-externally-managed --compile --install-headers /home/julka/LP/myproject/venv/include/site/python3.2 failed with error code 1 in /tmp/pip-build-cbu7a3/psycopg2
where it was compiling some lib.
Building with Python3.4

(venv)julka#Pyragas-vo2:~/LP/myproject$
Successful installation. I have put the log in pastebin.
Maybe I'm missing some kind of development files for python3.2, what do i need to check this out?
