Right, they could just run vacuum, and my 10% idea was bad because the
vacuum full would take an unpredictable amount of time to run depending
on whether it does a reindex.

One idea would be to allow VACUUM, VACUUM DATA (no reindex), and VACUUM
FULL (reindex).  However, as you said, we might not need VACUUM DATA ---
I am just not sure.
