Yes, in case you're connecting through a UNIX socket or when connecting
to "localhost". I suppose, you're running PostgreSQL on the same
machine, right? In that case, simply leaving out the "Host" config
option will let the plugin connect to the UNIX socket.

So, you're getting values on the local machine now? Do you get the same
values on the central server as well?
