<<itch>> This still seems like a serious oversimplification or
misexplanation to me.  It's true that a rule creates only one new query
to execute alongside each user-supplied query --- but that additional
query can execute upon many individual rows.  So I feel dissatisfied
with the above "clarification".  Can you think of another way to explain
it?
