This issue is fixed at 991a3df22.
Well, the bugs I was aware of ahead of PGCon are all fixed, but there are some new reports I still have to deal with. I left the existing open issue open, but maybe it'd be better to close it and start a new one?
I went ahead and closed it, and then started two new open items for the two new issues --- one is about assert failure and wrong query results due to incorrectly removing PHVs, the other is about inconsistent nulling bitmap in nestloop parameters.
