I agree with #1 on this.

The subdivision of superuserness is intended only for operations which
can't be used to directly give the user superuser access back and
therefore I don't think we'd ever put back CATUPDATE or an equivilant.

I'd much rather reduce the need for direct catalog modifications by
adding additional syntax for those operations which can't be done
without modifying the catalog directly and, where it makes sense to, add
a way to control access to those operations.

For example, changing a database to not accept connections seems like
something the database owner should be allowed to do.  Perhaps that'd be
interesting to allow users other than the owner to do, perhaps it
doesn't, but that would be an independent question to address.
