The confusing thing to me is perhaps just the name -- to me, "freeze_required" suggests that if it were set to true, it would cause freezing to happen. But as far as I can tell, it does not cause freezing to happen, it causes some other things to happen that are necessary when freezing happens (updating and using the right trackers). A minor point, no need to take action here. Perhaps rename the variable. I think 0001+0002 are about ready. -- Jeff Davis PostgreSQL Contributor Team - AWS
