Hi Chris,

please make sure that you have "tcpip_socket = true" in the
postgresql.conf file (located in /etc/postgresql on my system).
After that tune the parameters in the pg_hba.conf file located in the
same directory as postgresql.conf. Then restart your PostgreSQL server
and everything should be ok.
In the next release of pgAdmin it should be possible to connect directly
to the local socket without needing to configure TCP/IP listening on
server side.

Raphaël
