Thanks for this PR @Lordworms. To make sure that after conversion we indeed
produce correct result, it would be nice to have a test with data. Something
like
```sql
SELECT a, ARRAY_AGG(c ORDER BY c), ARRAY_AGG(c ORDER BY c)[1] as result
FROM multiple_ordered_table
GROUP BY a;
```
where we can determine index indeed points to correct value, after
conversion to `NTH_VALUE`. Other than this, this PR great.
