Review Comment:
hi @alamb, sorry for the mistake. Let me clarify my original thoughts. I
noticed that DuckDB provides full expressions for aggregations while only index
for group_by:
```
┌─────────────┴─────────────┐
│ HASH_GROUP_BY │
│ ──────────────────── │
│ Groups: │
│ #0 │
│ #1 │
│ │
│ Aggregates: │
│ sum_no_overflow(#2) │
│ min(#3) │
│ │
│ ~0 Rows │
└─────────────┬─────────────┘
```
But as you pointed out, it lacks test coverage — my apologies, maybe i can
finish it in the future :)
