VACUUM FULL's tuple-moving is definitely roll-back-able, so it might be
prudent to only do this for lazy VACUUM.  But on the other hand, VACUUM
FULL holds an exclusive lock on the table so no one else is going to see
its effects concurrently anyway.

As I said, it needs more thought than I've been able to spare for it yet
