ERROR:  ProvSQL: applying an SQL aggregate on top of a ProvSQL-introduced aggregation is not supported: the inner provenance() would be substituted with an expression containing an aggregate, producing a nested same-level aggregate that PostgreSQL rejects.  Evaluate the per-row provenance in a subquery and aggregate the resulting scalar outside, or drop the surrounding aggregate.
