There's no hostname in a socket directory.
Do you mean :"change the socket name from /tmp or /var/run/postgresql to something else?"
If so, then https://www.postgresql.org/docs/16/runtime-config-connection.html mentions sockets.

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.
