Review Comment:
On main this query fails like this:
```

CombinePartialFinalAggregate
caused by
Internal error: PhysicalOptimizer rule 'CombinePartialFinalAggregate'
failed, due to generate a different schema, original schema: Schema { fields:
[Field { name: "count()", data_type: Int64, nullable: true, dict_id: 0,
dict_is_ordered: false, metadata: {} }], metadata: {} }, new schema: Schema {
fields: [Field { name: "count()", data_type: Int64, nullable: false, dict_id:
0, dict_is_ordered: false, metadata: {} }], metadata: {} }.
This was likely caused by a bug in DataFusion's code and we would welcome
that you file an bug report in our issue tracker
