Oh, I had forgotten we had that mechanism already.  Yeah, that might
work.  I'm a bit tempted to design the option setting so that you can
select whether to keep the btree stats, the new stats, or both or
neither --- after all, there are probably plenty of databases where
nobody cares about the array-containment operators either.

That leaves the question of which setting should be the default ...
