I think it's taking that as '==' being the standard zone abbreviation and '.' being the DST zone abbreviation. If you wanted to restrict input to be the Olson-style zone names, you could do some kind of precheck, maybe insist on only letters/ slashes/underscores. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
