You can't really.  There is no part of our catalog-access
infrastructure that is designed to support this, and there are bits of
cached state all over the system that will misbehave if you try.
You found some of it, but there is plenty more.

I'd suggest letting the worker process die and spawning a new one
if you need to redirect its efforts to a new database.  If that
seems too expensive, rethink the design that requires you to do it.
