I see the names of a few people that also work on Postgres on this thread. We're not all that hard to get a hold of if you're a user that has some kind of feedback or question, for what it's worth. The culture is very open in that sense.

This is one of the goals of the zheap project. I myself have some very tentative ideas for tackling it within the standard table access method, heapam. I have not specifically committed to working on it on any timeframe. I haven't completely convinced myself that the approach I'm thinking of is truly robust and practicable. It's pretty complicated, especially because I cannot really know what will break and need to be fixed until I spend significant effort on the implementation.
