I'm curious how you'll do it, as I was once told that actually trying to
store heap data in a btree structure would be a non-starter (don't
remember why).
On a somewhat related note, I think that it would be advantageous if the
FSM had a means to prefer certain pages for a given tuple over other
pages. This would allow for a better way to keep heap and possibly index
data more compacted, and it would also be a means of keeping tables
loosely clustered. It would also make it far easier to shrink heaps that
have become bloated, because the FSM could be told to favor pages at the
beginning of the relation.
