Agreed- this seems like a good approach for how to address this. We
should still be able to end up with plans which use less than the max
possible parallel workers though, as I pointed out somewhere up-thread.
This is also similar to work_mem- we certainly have plans which don't
expect to use all of work_mem and others that expect to use all of it
(per node, of course).
Thanks,
