Обсуждение: Comment patch for index-only scans

If I recall correctly, Tom pointed out a while back that the comment
justifying the lockless read of the VM bit was not correct (or at least
not complete).

I rewrote it, but it was part of a patch that was not accepted. Attached
is the comment patch only.

Looks reasonable to me.
