Not necessarily an issue, but it might be better to just
execute this branch whenever row_batch is NULL since the
behavior is more predictable and there will be cases where we
free scratch_batch_ even when it's "not required" anyway,
e.g. if PHJ is enabled but not PAgg, or visa versa. Or e.g.
we specified do not enable PHJ but you used an anti join so
we spin up the PHJ regardless.
