I still agree with Robert that a052f6c is a bad idea. It's not the case
that that's blocking "any connected user" from causing an issue. The
temp schemas are always owned by the bootstrap superuser, so only a
superuser could delete them. All that that patch is doing is preventing
superusers from doing something that they could reasonably wish to do,
and that is perfectly safe when there's not concurrent usage of the
schema. We are not normally that nanny-ish, and the case for being so
here seems pretty thin.
