It'd be better to call it something like equivalent_tlists(), tlists_are_equivalent(), etc. (I'm not caring for the emphasis on the exprs either, because I think it'll also be necessary to compare resjunk fields for instance.) regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
