Hi,

I have postgresql  version 15 running on centos7.

I have below query that reads hostname from /tmp directory:

psql postgres -A -t -p 5432 -h /tmp/ -c 'SELECT pg_is_in_recovery();'


If you installed from the PGDG repository (possibly also the CENTOS repos, but I'm not sure), then the domain socket also lives in :
/var/run/postgresql

* I find that more expressive than /tmp.
* No need to specify the host when using sockets.
* Using a socket name makes parameterizing the hostname easier in scripts.
