Regression inb7b28c7c18. Refs #31377. Thanks Shai Berger for the report and reviews. test_aggregation_subquery_annotation_values_collision() has been updated as queries that are explicitly grouped by a subquery should always be grouped by it and not its outer columns even if its alias collides with referenced table columns. This was not possible to accomplish at the time10866a10landed because we didn't have compiler level handling of colliding aliases.
