Yeah, but if you do it there it's one added comparison (isOtherTempNamespace is very cheap, and you can get the namespace cheaply from the already-open rel). This way you need an extra syscache lookup because you are insisting on doing the check in a place where you don't have easy access to the pg_class row. Doesn't seem better. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
