Ah. Yeah, that would be true.

We do have mechanism that forces search_path to be recomputed across
changes of active role, but it's expensive to do that, and it seems
of rather debatable value to do it here --- it certainly wouldn't
improve Stephen's original problem, much less the other issues he
raises here.

What would people think of just eliminating the access-permissions
checks involved in temp_tablespaces? It would likely be appropriate to
change temp_tablespaces from USERSET to SUSET if we did so. So
essentially the worldview would become that the DBA is responsible for
the temp_tablespaces setting, not individual users.
