I don't think there is any chance for zheap to get into PG12.0.
However, we have made good progress by rebasing it over pluggable API
(thanks to Andres for doing the leg work for same). We have also made
quite a few performance improvements in the last few months. Right
now, we are doing some stress testing of the core zheap and trying to
finish the remaining things like support for logical decoding. Also,
we are trying to make progress on the undo patches by reviewing the
code which is one of the building blocks for zheap. I request you to
help in review/test of zheap if you want to see more progress on the
same.
