Hi,

I think the right approach would be to do all of this in heap_insert and
heap_multi_insert. Whenever starting to work on a page, if INSERT_FROZEN
is specified, remember whether it is either currently empty, or is
already marked as all-visible. If previously empty, mark it as all
visible at the end. If already all visible, there's no need to change
that. If not yet all-visible, no need to do anything, since it can't
have been inserted with COPY FREEZE.  Do you see any problem doing it
that way?

Greetings,

Andres Freund
