Well, the only privilege we have now is "CREATE", which allows creation
of any kind of object inside a schema. I'm generally in favor of
providing more granluar 'create table', 'create view', etc privileges
that can be granted out at the schema level, and 'create policy' would
be appropriate to include in such a set of object-creation permissions.
I don't have any particularly genius ideas about where we'd get the bits
to implement such a grant system though. We could modify the existing
grant system to use larger bits, but given that this would only be
applicable for schemas, perhaps it'd make sense to have another field
in pg_namespace instead? Not sure, just brainstorming here.
Thanks!
