Oh, I'm sorry, it's using hashtable existence to condition the whole
output. So my complaint is backwards. I thought the intention was
to print the estimated number of batches in all cases, and then the
actual as well in EXPLAIN ANALYZE.

BTW, I think "estimated" and "actual" would be less confusing
terminology than "original".
