OK, I pushed this after re-reviewing it and fixing a number of
oversights. There remains only the task of adding max_parallel_degree
as a system-wide limit (as opposed to max_parallel_degree now
max_parallel_workers_per_gather which is a per-Gather limit), which
I'm going to argue should be a new open item and not necessarily one
that I have to own myself. I would like to take care of it, but I
will not put it ahead of fixing actual defects and I will not promise
to have it done in time for 9.6.
