AFAIU, cursor_plan_rows() has some serious limitations like requiring to
be executed for a portal. I was planning to make estimated_count() work
for nodeAgg and custom calls too - as count() does.

But OTOH, Tom's complaints look like still applicable for my
estimated_count() too. Does this TODO need a little bit more
clarification or we can count is a redundant one?
