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.
