Source 
pub fn plan_aggregate_clauses(
    select: &Select,

Expand description

Plan the aggregate clauses of select against scope.

table_columns holds the declared columns of a single-collection source, so a GROUP BY name that is an input column wins over a SELECT alias. A join passes an empty slice. order_by is the enclosing query’s ORDER BY, read only to learn whether it names an aggregate of its own.
