Well, global settings and per-user settings are clearly global. I'm not
sure that per-database settings are "logically" global, although I'll
accept that's how they're stored.
At present it means you can't reliably do: DROP DATABASE foo; pg_restore --create foo.dump
I'd then have to either hand edit the dumpall dump or wade through a
bunch of errors checking that none of them were relevant.

Yep, but that will give you a "no such role" error when you try to
restore. This is a situation where you can restore without errors and
end up with different behaviour: dd/mm/yyyy vs mm/dd/yyyy or text-search
stop-words changing.
