I'm a bit uncomfortable with removing the sanity check; it seems like a good thing to have, especially since this code hasn't even made it out of beta yet. AFAIK the "<>" case is purely hypothetical, because we have no index opclasses supporting such an operator, no? How about just documenting that we'd need to remove the sanity check if we ever did add support for such a case? regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
