A local user with the superuser privilege would not be able to log into
another database, because superuser doesn't give you any extra privilege
until you've logged in.

Yeah, as superuser you could still break things as much as you pleased,
but not through SQL.

I share your doubts as to how useful such a concept actually is, but
it'd work if we had real local users.
