And now it's time to revert. Proposed patch attached. Though we didn't get any [grease] emails to the list, I think this was a success. There are recent issues and PRs on GitHub that reference this, and we flushed out an issue with Debian's upgrade wrappers that matches the bug that pg_upgrade itself had, and there's even anecdotal evidence that a correct negotiation implementation can survive contact with Copilot's incorrect review advice. Woohoo! Jelte, thanks again for the idea. I think we should try to develop a production implementation of this for PG20. --Jacob
