FWIW, my concern was always limited to that. I don't actually mind if
we use the "degree" terminology, as long as our usage is consistent
with that of other major systems. Since the GUC's behavior isn't going
to change now, the terminology should change. I'm fine with that. I'm
not particularly concerned with the specifics of some new terminology,
as long as it's consistent with the idea of auxiliary worker processes
that cooperate with a leader process.
