I believe we're talking about reverting 77cd477c4 (in 9.6 only not
master), correct? It's a little harder than just "git revert" because
of the subsequent max_parallel_degree -> max_parallel_workers_per_gather
name change, but still not exactly rocket science.
Since 77cd477c4 was your commit, I'd sort of expect you to do the
honors, but if you don't want to I can.
