Missed that in my previous reply.
If host part of the URI points to localhost, the UNIX domain socket would be considered by libpq just as if you would pass "-h localhost -p 5433".
But what if the user wants to connect exactly via socket or TCP/IP ? And what if the user needs to specify a socket file name extension?
