We use MaxOffsetNumber with index pages as well.
At quick glance, the only places I can see where we could replace
MaxOffsetNumber with MaxHeapTuplesPerPage, are in vacuum.c and
vacuumlazy.c, where we allocate arrays big enough to hold potentially a
full page's worth of tuples. We could change those, but it's hardly
worth the trouble.
