I installed postgres from brew.
I got an error, I tried to delete the postmaster.id
The file seems to be missing.
rm -f data/postmaster.pid
It had no effect.
I tryed
$brew install postgres

$postgres --version

I don't know why you insist in wrecking your PostgreSQL server by removing the PID file. I wish you would stop doing that.
The error message means that you are trying to connect to database t, but that database does not exist. Since you do not explicitly specify a database, the causes could be:
you are operating system user t, so the connection defaults to database t
the environment variable PGDATABASE is set to t
the environment variable PGUSER is set to t, and the connection defaults to the same database name as the user name
In any event, the solution is to pick an existing database and use
psql -d dbname

I'm working on a Phoenix/Elixir project which is managed using nix-shell. I'm having issues regarding postgres setup.
I'm starting server using pg_ctl -D $PGDATA start and it outputs as:

Any help would be appreciated, thanks.
You have to tell createuser to connect via the socket in /tmp:
createuser -h /tmp -U postgres --createdb --echo newuser
You've set a custom path in the postgres config, so you probably also need to specify that with pqsl / createuser. In other words createuser -h /tmp/ ....
I run Windows and I am trying to install postgres, but I can't get it to work. During installation, I get the error:
Failed to load sql modules into the database cluster
When I try to access the server in pgadmin or via SQL Shell, I get the error:

Can someone please help me?
I had the same issue and followed different tips and tricks available on the internet but nothing worked.
I fixed that issue by following these steps:
First disable antivirus for an hour
Create a folder in either C drive or D drive and give full permission to User
Then again install a fresh application. If you have already installed then uninstall that and install from starting.
Make sure to choose that folder only at the time of installation
I'm doing the same steps as described in: https://medium.com/better-programming/connect-from-local-machine-to-postgresql-docker-container-f785f00461a7
but when I try to connect to my postgres (with password mysecretpassword) from Intellij I get the following error:
The specified database user/password combination is rejected: [28P01] FATAL: password authentication failed for user "postgres"
Of course I can connect to my db from cmd command:

It seems that you have running postgresql instance on 5432 port. Check what is running on port 5432:
sudo lsof -i :5432
If there are any records, you could manually kill the processes that are using this port (man kill) and re-run docker container. In my case there was another local instance of postgresql running on this port, so the following helps me:
sudo pkill -u postgres
Or (more preferable) just specify a different port mapping for your docker postgresql (for e.g. 5433):
docker run -p 5433:5432 ...other_your_flags... postgres:latest
try to remove your PostgreSQL the one you have installed locally, if it exists. Because my problem was precisely that the idea did not understand where to connect, to the docker survey or to that installed database on my computer
I am unable to start the Postgres server and whenever I use pg_ctl I am getting the following error - can some one help me to fix this. I changed the folder permissions using CHmod and tried running with Sudo -s also but still the problem exists.
one error I did was, I deleted the Postmaster.pid when the server was running- post this I am getting this issue when ever I try to start the server through pg_ctl and another error when I use the pgadmin.
Any suggestions here will be really helpful- thanks.

Disclosure: I am an EnterpriseDB employee.
Try running this code
pg_ctl -D /usr/local/var/postgres start
I am trying to set up a new instance of PostgreSQL 9.6 on a machine. I have tested it on another machine and its working fine on that machine. But the same process is not working on new machine. Below are the steps I am using
created a new data directory with below command
/opt/rh/rh-postgresql96/root/bin/initdb -D /var/lib/pgsql/9.6/data/
created a service file /etc/systemd/system/rh-postgresql96-inst2.service with below content
.include /lib/systemd/system/rh-postgresql96-postgresql.service
[Service]
Environment=PGDATA=/var/lib/pgsql/9.6/data/
Environment=PGPORT=5433
User=postgres
Group=root
registered service using command systemctl enable rh-postgresql96-inst2
now using command systemctl start rh-postgresql96-inst2 to start service.
All these steps are working fine on one machine but not on the 2nd one.
I am getting below error while starting service on the 2nd machine

systemd[1]: rh-postgresql96-inst2.service failed.
However, I am able to start service using pg_ctl.
Also, I have checked with netstat, lsof command to check if any other postgresql instance is running on port 5433 but its not the case.
Infact i tried 5431, 5434 ports also but server is not starting up
Instead of turning of SELinux you should allow postgres to bind to port 5433 in SELinux.
There is a port parameter postgresql_port_t which by default has port 5432 and 9898.
semanage port -l | grep post
postgresql_port_t tcp 5433, 9898
What you could do is simply add port 5433 to this list.
semanage port -a -t postgresql_port_t 5433 -p tcp
semanage port -l | grep post
postgresql_port_t tcp 5433, 5432, 9898
After that you can start your postgres server listening on port 5433
systemctl enable rh-postgresql96-postgresql
systemctl start rh-postgresql96-postgresql
netstat -tulpn
tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN 2847/postgres
tcp 0 0 127.0.0.1:5433 0.0.0.0:* LISTEN 2775/postgres
There is also a handy tool called audit2allow to help debug selinux problems.
audit2allow -m whatiswrong < /var/log/audit/audit.log > /root/showme.te
The file showme.te show you why SELinux is not allowing the service to do what you need.
You should not turn off SELinux just because it's hard to understand or if you don't know how it works. Instead you should study it :)
I reccomend this lecture from the Red Hat Summit https://www.redhat.com/en/about/videos/summit-2018-security-enhanced-linux-mere-mortals
This issue was related to SELinux.
When I run command sestatus on both machines, output was a little bit different.
One server had Current mode: permissive and 2nd one had Current mode: enforcing.
So I changed the current mode to permissive on the 2nd machine using command setenforce 0.
and it resolved the permission related issue. Now I am able to start 2nd instance.
