Good point. I _think_ the registry is safe to set up and use in
single-user mode but not in a regular postmaster process. It'd probably be
wise to add some assertions along those lines, but even if we didn't, I
think the DSM code has existing assertions that will catch it. In any
case, I'd like to avoid requiring folks to add special
single-user-mode-only logic if we can avoid it.
