I agree with the new heap section, and your patch on that looks good.
While on it, I have one suggestion: fsm_page_contents does not have an
example of query.  Could we add one while on it?  An example
consistent with the other function's examples:
=# SELECT fsm_page_contents(get_raw_page('pg_class', 'fsm', 0));
