I meant a max_worker_processes setting, which of course is different.
Nevertheless, I find it surprising that max_parallel_degree = 1 does
not prevent parallel operations, and that max_parallel_degree is
defined in terms of the availability of worker processes (in the
strict sense of worker processes that are launched by
LaunchParallelWorkers(), and not a broader and more practical
definition).
