I just read an article about the advantages of zheap over the heap that PostgreSQL currently uses and there were several posts on this list about it being more compact as well as more performant. I am hopeful that it makes it into PostgreSQL 12.0, but it is unclear what the current status of this change is.
Can one of the Postgres devs please chime in on its status for 12.0? Thanks, Michael Goldshteyn
