I don't have a clue why it's like that.  It seems like it should be
PGC_USERSSET just like, say, work_mem.  I think that's just brain fade
on my part, and I think the current setting will be really
inconvenient for unprivileged users: as it is, they have no way to
turn parallel query off.  Unless somebody objects, I'll go change
that.
