Two problems. The first is the one Karsten already mentioned about the difference
on ports. Second you have not specified a host so Psycopg is trying the local
socket. If you are trying to connect from a machine other than the other one
with the Postgres server it is not going to find the socket. Also the socket
connection may have a restriction in pg_hba.conf that would prevent a
connection.
