Well, the "bloat" aspect of it is really the least of our problems.
AFAICT what is happening is flat-out index corruption, that is, an
intended update isn't applied where it should be but to some
seemingly-random other page. If this is common then it seems like we
ought to be hearing a lot of reports of query misbehavior on slaves.
