> Regression from Calcite-750 Allow nested window aggregates. 
> Calcite allows illegal queries instead of raising an appropriate error. When executing the following query calcite does not raise the following error.
> {code}
> select avg(sum(b)) over (partition by b) from t1;
> ERROR:  Expression 'b' is not being grouped
> {code}
