In the context of an upgrade, any node started is isolated with its own port and a custom unix domain directory with connections allowed only through this one. Saying that, I don't see why forcing max_logical_replication_workers to be 0 would be necessarily a bad thing to prevent unnecessary activity on the backend. This should be a separate patch built on top of the main one, IMO. Looking forward to seeing the rebased version you've mentioned, btw ;) -- Michael
