I'm fine with either of these ideas. If I had to choose one, I'd just remove the autovacuum_worker_slots report for the reasons Tom noted. However, weren't we considering reverting some of this stuff [0]? I see that sawshark is now choosing max_connections = 40 and autovacuum_worker_slots = 6, and since there are no other apparent related buildfarm failures, I'm assuming that nobody else is testing the 60 semaphores case anymore.
