Well, I'm not sure that it would actively break anything, but we
definitely meant to disallow the case. Also, I seem to recall some
places that intuit a relation's shared marker in the opposite direction
(if it's in pg_global it must be shared), and that could definitely
cause issues if we treat a rel as shared when it isn't.
