I agree that we do *not* want to force role creation on schema creation.

I don't entirely get what you're suggesting here considering we already
have $user, and it is the first in the search_path..?

No, I don't think we're going to get rid of it.

That really isn't the same..  In this approach, regular roles are *not*
given the CREATE right on the database, the system would just create the
schema for them on login automatically if the role attribute says to do
so.
