Postgresql Database Job Failure

I am getting the following error while setting up postgres to run my tests. This was working fine till couple of days back and suddenly stopped working.

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

Data page checksums are disabled.

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

    pg_ctl -D /var/lib/postgresql/data -l logfile start

Can someone please tell me what am I doing wrong?

Hi buddy, did you find the answer to this question? or who fumbles how to make postgres not terminate after its creation, please give an answer

Yes, I did. Thank you.

What was the fix?

Can you please share the solution.

I do not recall the solution. Looking back I should have added the solution here. I checked this config with the current config and the only difference is POSTGRES_DB value. Not sure what if that solved it though.
