Well, if you look into pg_operator you'll soon find that there are exactly two built-in operators that accept type xid: "=(xid,xid)" and "=(xid,integer)" (where I'd say the latter is just a kluge). There hasn't previously been any demand to flesh it out more than that. Do you have an actual use-case where <> would be helpful, or is this just experimentation? regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
