  Strange, they really wanted it for 13 and allowed it to be committed post feature freeze, but then all discussions stopped after April. And I couldn't find anything else in the mailing list.

    There was a long discussion about multiple patches that "almost made it" on an internal release list. Ultimately, the conclusion was not to push them after the code freeze date (which was already extended by a week). Obviously, it'd be great to get those patches in, but there's always the risk of pushing something that may not be quite ready yet, did not go through sufficient review etc. Which might disrupt the whole release schedule, make the stabilization phase longer, etc. And all the lockdowns around the world just amplify the risk. There's also the question whether it's worth breaking the rules the project adopted over the years. Considering all this, it probably makes sense to leave this for v14 ... But yeah, it'd be great to have this in v13, had it been ready before the code freeze.

      Thanks. At least we know it should be coming in PG 14. Hopefully Zheap too.

  This earliest this will be available is PostgreSQL 14; it was not added to PostgreSQL 13.
