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 could warn
him not to do so before we really stress tested it.

Is that a compromise?
