Heikki Linnakangas 588f50f851 Don't assume that PageIsEmpty() returns true on an all-zeros page.
It does currently, and I don't see us changing that any time soon, but we
don't make that assumption anywhere else.

Per Tom Lane's suggestion. Backpatch to 9.2, like the previous patch that
added this assumption.
