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.
