OK, here's a little trick you may not be aware of.
pg_connect("dbname=mydb user=stan");
will open a local unix domain socket.
pg_connect("host=127.0.0.1 dbname=mydb user=stan");
will open a local TCP/IP connection on the loopback interface.
In order for this to work, your postgresql.conf must have this line
changed:
#tcpip_socket = false
to
tcpip_socket = true
and your pg_hba.conf needs a line like this:
host all all 127.0.0.1 255.0.0.0 trust
So it's likely the "secure by default" mentality of postgresql that's
biting you here.
