I've seen similar problems resolved by discovering that (1) the DBA
was editing the wrong copy of the pg_hba.conf file, or (2) there was
actually more than one postmaster running on the machine.
Check "ps" for multiple postmasters. Put a deliberate error in the
pg_hba.conf file and verify that the postmaster fails to restart.
