I am not convinced on this point. Why is per-server not good enough? The
obvious place to make these changes seems to me to be during or
immediatly after the bootstrap phase of initdb. It would avoid a host of
later troubles.

I don't think we should rush at this. All of these solutions are based
on the existing structures. I have started thinking about a solution
that would involve keeping two versions of catalog names: a canonical
name and a "name as supplied at creation". There would be heaps of
wrinkles, but it might get us where we want to be. But I have not had
time to sort it out in my head yet, let alone make any experiments.
Let's keep getting more ideas.
