I agree that the features don't have to define the catalog
representation. On the other hand, I don't think we'd want a change to
the 'default defaults' to affect existing objects in the system.

I don't really see it as a frequency thing, to be honest.. I see it as
dependent on the user base and what the users are allowed to do. I run
quite a few different databases with different roles. I've also got
lots of users that aren't DBAs but need to be able to create tables,
sometimes create schemas, etc. What typically ends up happening is that
they'll create a schema and be running along happily, until one day
they're out, and someone else needs to do something with that schema.
Then it's a support request to me, even though that schema should have
had 'usage' to public from the get-go because there's nothing sensetive
in that database. I've got cases where the user who created the schema
doesn't know how or doesn't think they can change the permissions
themselves too, more calls to me.
Being able to set up the defaults on the database when we create it
(that's not something we let non-admins do, at least.. :), depending on
what the role of the new database is, would be quite nice. Being able
to do it for certain objects in schemas has certainly helped. Doing it
for more objects (like schemas) seems like a natural next-step to me.
Doing it for schemas is inherently "database-wide", as that's the
container which schemas exist inside of. Thinking on it a bit more,
the 'database-wide' options for objects which exist inside schemas could
just be what new schemas are initialized with for their defaults using
the existing system. If schemas are created before that's done, there'd
be a bit of pain going back and updating them, but that's not a big
deal, imv.
I do still think it'd be nice if we displayed the *actual* ACLs in \dp
instead of just 'blank'. Also, do we really not sure a function's ACL
in any \df*..? :/
Thanks,
