The "VACUUM FULL" synonym of "CLUSTER" doesn't depend on whether the target is pre-clustered, and both will run against
thetable if the user has run an ALTER TABLE..CLUSTER ON.  Now, we could try to catch that latter command with a utility
hook,but since the VACUUM FULL is still problematic, it seems cleaner to just add the callback I am proposing.
