Can we please, please, not spread the discussion out any further. It's
bad enough that we're already discussing on separate threads on -bugs
and -performance.

Pft. In most cases it doesn't actually matter that much because the
contained query are the expensive stuff. It's just when you do lots of
very short and cheap things that it has such a big effect. Usually the
effect on the planner is bigger.

That said, I don't mind improving the docs here, they're not easy to
grasp. But it probably shouldn't be in plpgsql's docs, but rather the
general function ones.
