Everything that you've said looks fine, so the problem is somewhere you're
not looking :-(. At this point, I'd wonder if the pg_hba.conf file you're
changing is the same one the postmaster is reading. You might try
confirming that directly by inserting a syntactically-incorrect entry and
seeing if the postmaster bleats about it to the postmaster log when you
issue a reload.
