The last requirement seems completely contradictory to the other three.Either we're trying to make databases even more
isolatedas
 
multi-tenant Catalogs, or we're not.  Trying to do both at the same time
is failure-by-design.

Given that we offer schema as an alternative to multiple databases, and
users are starting to get used to them, I think that requirement (4) is
just a bad idea, and not worth pursuing, except in the context of pgsql_fdw.
