      Description

      CALCITE-1069 removed the indicator columns for Aggregate operators. In some places, the indicator boolean check was replaced by the following check: aggregate.getGroupSets().size() > 1. However, that check is incomplete, it should have been replaced by aggregate.getGroupType() != Group.SIMPLE.
