wonderedif there would be complaints about that.  If so, we could instead leave CREATEROLE alone, and create some other
privilegedrole for the same thing, but it does start to look funny having a CREATEROLE privilege bit and also a
privilegedrole named, perhaps, pg_can_create_roles.
 


Give that CREATEROLE currently just about amounts to being a superuser,
maybe there should be a pg_upgrade option to convert CREATEROLE to
SUPERUSER. I don't want to perpetuate the misfeature though, so let's
just bring it to an end.
