My bet is that you have the Postgres server configured so that it
only accepts Unix-socket connections and not local TCP connections
(which is what the SSH tunnel will try to connect to).  If you do
"psql -h localhost" on the remote server, does it work?

If not, you need to fool with listen_addresses and possibly your
pg_hba.conf setup.
