The "VACUUM FULL" synonym of "CLUSTER" doesn't depend on whether the target is 
pre-clustered, and both will run against the table 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.
