Compare this:

"max_parallel is the maximum number of parallel workers which will work
on each stage of the query which is parallizable.  If you set it to 4,
you get up to 4 workers."

with this:

"max_parallel_degree is the amount of parallelism in the query, with the
understanding that the original parent process counts as 1, which means
that if you set it to 1 you get no parallelism, and if you want 4
parallel workers you need to set it to 5."

Which one of those is going to require more explanations on -general and
-novice?  Bets?

Let's not be complicated for the sake of being complicated.
