> A possible approach to support rewriting queries with an aggregate with
> grouping sets is implementing a rule that splits the aggregate in the query
> into an aggregate without grouping sets (bottom) and an aggregate with
> grouping sets (top). Then the materialized view rewriting rule will trigger
> on the former.
