Postgresql won´t start

I recently installed postgresql on my system following: https://developer.fedoraproject.org/tech/database/postgresql/about.html. All fine until i went to the second step " Controlling access to PG cluster". After doing changes to my pg_hba.conf and typing “sudo systemctl restart postgresql” it failed saying “Job for postgresql.service failed because the control process exited with error code. See “systemctl status postgresql.service” and “journalctl -xeu postgresql.service” for details.”. Output of systemctl status postgresql.service:

I googled the topic myself and got it to work by deleting the /var/lib/postgres/data directory and setting it up again. But now i got the same issue again. (Same error logs).

I also enabled the postgresql.service when it was still working and i ran “initdb -D /var/lib/postgres/data” as the postgres user to initalize the database cluster.

I correctly set the permissions for the directory (0700) and my /var/lib/postgres/data directory is not empty, which seemed to be the issue for most people getting the issue.

There may be better clues in postgresql’s log directory. What do you see there?

Thanks for the reply. Sadly the log isn´t really helpful. However, i found this post https://bugzilla.redhat.com/show_bug.cgi?id=1983824. I didn´t mention, that i’m also trying to use postgresql with a java program and jdbc. And both times it crashed was after trying to run the program (didn´t see the connection, my bad). I’m most likely experiencing the same issue. He did say that he managed to get it to run but sadly not how. I also don´t get the server up at all right now. Deleting the data directory and initalizing the db again didn´t help. They did talk about a misconfigured pg_hba.config file so i might play around with that a little.
