I have a big patch set pending that does this (which I dubbed
"page-level freezing"), plus a bunch of other things that control the
overhead. Although the basic idea of freezing all of the tuples on a
page together appears in earlier patching that were posted. These were
things that didn't make it into Postgres 15.

I should be able to post something in a couple of weeks.
