That's certainly an option. It might be noise in some situations. On
the other hand, it affects whether attaching the partition is O(1) or
O(n), so somebody might well want to know. Or maybe they might be
more likely to want a message in the reverse situation, telling them
that the partition constraint DOES need to be validated. I'm not sure
what the best user interface is here; thoughts welcome.
