It's a *huge* issue. For one, the computational effort of doing so would
be a problem. But there's a more fundamental issue: We don't even know
the type of the page at the time we write data out! We can't do a lookup
of pg_class in the checkpointer to see whether the page is a heap page
where we need to mask out hint bits.
