and, furthermore, the default pg_hba.conf (in the source distribution,
at least) does not allow any sort of authentication via tcp. You need
to add the appropriate line(s) such as...
host all all 0.0.0.0 0.0.0.0 md5
(which will allow any IP address to authenticate as any user on any
database via md5 password encryption... there are many other choices and
combinations possible, see $PGDATA/pg_hba.conf and the PostgreSQL
documentation for more information on authentication).
