I don't know that stuff off the top of my head and it also has recently changed. The v13 documentation will be more useful than I for those specifics. > > I don't know what the warnings are - they read like something that should crash the server... I'd not noticed those messages before. Reviewing another instance, I did see a few before it started into what I recognize as the "normal" sequence of applying WAL. My subsequent theory about confusing containers and starting a second PG instance, was itself the result of confusion, and I had not done that after all. On a second try, it did the same thing, I left it alone, and it eventually came up. I'd still like to understand what those warnings are, and why I usually see only a handful followed by a lot of messages about WAL having applied, but this instance I see a lot of these, and then the server claims all is good without a log of those messages about WAL being applied.
