Can we edit the socket to change the hostname in it ?
On Ubuntu 22.04 install, given:
srwxrwxrwx 1 postgres postgres 0 Apr 22 14:01 .s.PGSQL.5432=
-rw------- 1 postgres postgres 68 Apr 22 14:01 .s.PGSQL.5432.lock
The contents of .s.PGSQL.5432.lock(the file that indicates a Postgres
instance has a lock on the socket) are:
862
/var/lib/postgresql/15/main
1713795311
5432
/var/run/postgresql
There is no hostname to be changed as you are working with a local socket.
Regards.

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.
