What you've probably run into here is that some packagers build Postgres
to put the server's socket file into /tmp, while others build it to put
the socket into /var/run/postgresql/ or some similar path. Likely,
you are now using a new version of libpq.so that expects the latter
while your server is still doing the former. You can override libpq's
default with "-h /tmp" or equivalent in order to connect.
