That works as well. Now this code really has been written so as we don't want to do this useless computation for non-Assert builds, that's why I did not suggest it. But as it does just a list_nth call, that's not really costly... And other code paths dealing with the cost do it as well. -- Michael -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
