I had always figured that you could use bki to recover from these things,
but a quick attempt shows that you can't.
You proposal makes sense from a Unix admin point of view (booting into
single user mode without password). Since we have a check against root
access and against too liberal PGDATA permissions, I think this would be
safe. Possibly we need to guard against setgid problems as well.

Definitely BKI land. But that usecatupd field does make some sense,
apparently.
