Wouldn't pg_ctl

In UNIX, each process runs with the permissions of the user that starts the executable, not the owner of the executable (unless the SETUID flag is set).
So it doesn't matter who owns pg_ctl
, but you have to be user postgres
when you run it.
My point was that I would thinkpg_ctl
would be the way of getting this to other users, instead of having to log in as thepostgres
user to see what the status is of the db server. It's a bit odd to jump through those hoops. Ah but then again, in a db-only deployment, that's probably the case I'd bepostgres
. I just thought they would allow tools available to normal users, or at leastsu
.

This needs few troubleshooting steps to pinpoint the real issue.
- Find out the user/owner and files permissions for that location in Linux:
Ls - al /var/lib/pgsql/data/
ls - al /var/lib/pgsql/
Try to change to the postgres user and access the directory in 1
# su - postgres
Following links should fill in blanks for few steps to check things out. On #2 link, you aren’t moving the dir, but you see steps to ensure dir is ready/accessible

Update
From comments, it looks like pg ctl is run as user x... and lacks sufficient permissions
Without knowing much about your environment, it may be better to let postgres be that user who runs pg ctl since it’s already doing stuff related..
Sorry, I think you've missed what I put. It is owned postgres:postgres. I stated that in the original post. pg_ctl is run as rich and it can't see inside/var/lib
. The database works. I just can't usepg_ctl status
due to the permissions that the install set itself. It's odd.
