BTW, the 2X amplification for intermediate `Rows` seems to be conservative,
but it is still not enough for some of the queries. The following query creates
`Rows` larger than the original batches, and the query will fail when reserving
memory for `Rows`:
```
-- sort-tpch Q5: 3 sort keys {(INTEGER, 7), (BIGINT, 10k), (BIGINT, 1.5M)} +
no payload column
SELECT l_linenumber, l_suppkey, l_orderkey
FROM lineitem
ORDER BY l_linenumber, l_suppkey, l_orderkey
```
This can be worked around by configuring a larger
`sort_spill_reservation_bytes`.
