If this were a bug fix, it'd be a candidate for back-patch, which IMO it's not --- if only because of the risk of plan destabilization. But for a more direct analogy, if you'd submitted some other improvement in selectivity or cost estimation, that was not a bug fix in the sense of "corrects outright wrong answers", would you expect it to escape feature freeze at this point? Beta or no beta, there has to be a pretty good argument why changes should go into v11 and not v12 once we're past feature freeze. regards, tom lane
