I should add: I think that the chances of this patch destabilizing the
code are very slim, once it receives the proper review. Certainly, I
foresee no possible downside to not inserting the doomed IndexTuple,
since it's guaranteed to have its heap tuple super-deleted immediately
afterwards.

That's the only real behavioral change proposed here. So, I would
prefer it if we got this in before the first stable release of 9.5.
