A similar wrapper function to the one shown here: http://archives.postgresql.org/pgsql-general/2005-06/msg00709.php should work. But I agree with the other folks in this thread who have questioned whether this is a good idea: backend APIs are known to change significantly between releases, and making assumptions about how they behave seems like asking for trouble to me. -Neil ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
