I assume you're not particularly interested in doing that? I'm more than
happy to leave this to others, but if nobody signals interest I'll give
it a go, because it'll get a lot harder after the pluggable storage work
(and it'd work even less usefully afterwards, given the location in
heapam.c).

Greetings,

Andres Freund
