Yeah, I was thinking the same thing while preparing my docs patch.
At the risk of opening another can of worms, what about renaming
max_worker_processes as well? It would be a good thing if that
had "cluster" in it somewhere, or something that indicates it's a
system-wide value not a per-session value. "max_workers_per_cluster"
would answer, though I'm not in love with it particularly.
