I'm not sure I understand what the problem is. We got to get the
information for the fsm from somewhere? Are you arguing we should
instead have it included as an explicit xlog record payload? Or just
that it should use PageGetExactFreeSpace()? I assume the former based on
your "what business" language, but that'd not make terribly much sense
to me. I don't think precision terribly matters here...
