Hi Shreyansh ,
Thanks !!!
The issue was different in file permission . So now I am able to log in . But can not start this postges instance (running on different user apart from postgres) as a systemd utility . Only way to start or stop the instance is pg_ctl . Even after changing PGDATA in systemd file and reloaded .
What could be issue if my postgres is not running as a service from root .
Thanks
Soumitra

In addition to this.
Try with below command
psql -p db_port -d dbname -U username
What error did you face during connectivity?
Hi Shreeyansh ,
Thanks for the response .
I installed postgres 10.0 rpm . It created osuser postgres and executed initdb and cluster is up and running .
Then I took my current user (not root) to create another cluster using initdb . It successfully created but I am not able to log in to the new cluster using psql and current user(through which initdb was executed).
Thanks,
Soumitra
Hi Sumintra,
You have to create a postgres OS user,initdb must be run as the user that will own the server process, because the server needs to have access to the files and directories that initdb creates. Since the server cannot be run as root, you must not run initdb as root either. (It will in fact refuse to do so.)
Hi ,
I am using RHEL to install Postgres 10 and setting up replication . But in my OS no postgres user exists . Installed it with sudo access . Can I run the postgres DB with all it's utility (like psql, vaccumdb , pg_rewind , initdb etc.) along with Master slave replication, archival process without postgres user.
If it can be done , do I need to follow any extra step to the os user apart from postgres ?
Is there any way to skip postgres os user ?
Thanks ,
Soumitra
