I think the way it is currently in HEAD seems easy to correlate how the
feature works, but may be it appears to me that way because I am involved
from long time with this implementation. I also think one can easily
confused among max_parallel_workers and max_worker_processes, so if we want
to change, my vote goes with changing the default of max_parallel_degree to
1 (as suggested by Peter G.).
