> I looked through all callers of this method, and in each case we have a fresh
> List object anyway, and hence the wrapping is not necessary saving at least
> one new object per row scanned.
> This is probably not really critical, but of a sizable COUNT(\*) or other
> aggregate it still creates lot of unnecessary objects.
