In theory it should work, in practice, I don't know.
Since pg_class is really close to the heart of the system, it is created a little different during bootstrap. This
causes, that setting relacl to storage 'x' doesn't automatically create a toast relation for it during
bootstrap. And therefore, the toaster should only try to compress, never move out (to where?).
Someone could later create such a toast table with ALTER TABLE ... if he wants to give it a try. And we
couldwarn him not to do so before we really stress tested it.
Is that a compromise?
