Hm, yeah, the first time would throw an error because pg_temp doesn't
resolve, so if you're using DROP IF EXISTS there would be a visible
difference in behavior between the two cases.
I wonder if DROP IF EXISTS should consider non-existence of the
specified schema (if any) as being a "not exists" case, and not throw
an error for it. This isn't specific to the temp schema at all IMO.
