it working fine but when i try with psql i'm getting error as below
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

I have installed postgresql for a long time, but it suddenly stopped working when I added an IP address in the pg_hba file.
I'm trying to run it using sudo service postgresql restart but this doesn't work.
Also
root#ubuntu-dev-server:/# systemctl start postgresql#9.6-main
Job for postgresql#9.6-main.service failed because the service did not take the steps required by its unit configuration.
See "systemctl status postgresql#9.6-main.service" and "journalctl -xe" for details.
And then,
root#ubuntu-dev-server:/# systemctl status postgresql#9.6-main.service

I have tried several things but still do not start. Any recommendation is welcome.
One day, My Postgresql server stopped working. Checked log. It was shutdown somehow.

It complained that there are no files and directory. so I checked if my postgresql running.

Don't know what to do more. Is anybody had the same problem?
More infos.

That's pretty clear, isn't it?
The Ubuntu PostgreSQL startup script wants that postgresql.conf and/or pg_hba.conf be owned by user postgres, else it refuses to proceed.

I read that doing sudo service mongodb start might solve your problem but I fear will it delete my data?
An exit code 100 for the mongodb service means that it could not access or find the data directory. If your data directory is protected by sudo then starting the service with sudo will solve your problem.

I would look at /var/log to see if it wrote a log.
If it did not, I would attempt to start it manually to the database:
su - postgres
postgres -d 5 -D /var/db/postgres/data96
The -d 5 command sets debugging to level 5. The -D command tells PostgreSQL where the database files are. The above directory is the location where PostgreSQL 9.6 runs on FreeBSD. If you are running Ubuntu, the directory should be /var/lib/postgresql/[PostgreSQL version]/data/. The PostgreSQL default data directory is /usr/local/pgsql/data.
