Thread: pgsql: Have psql avoid describing local sockets as host names.

Log Message:
-----------
Have psql avoid describing local sockets as host names.

We now use the phrase 'via local socket in' rather than 'on host' in both
\c and \conninfo output, when applicable.

Fujii Masao, with some kibitzing by me.
