> Rewrite last_value to first_value to enable streaming results
> last_value cannot be streamed because the intermediate results need to be
> buffered to determine the window result till we get the last row in the
> window. But if we can rewrite to first_value we can stream the results,
> although the order of results will not be guaranteed (also not important)
