    Description

      If a  MERGE statement lists no WHEN MATCHED THEN DELETE or WHEN MATCHED THEN UPDATE clause, the merge query should not contain the position values of the target table. It should be handled in analyze time and requires a different evaluation at the Iceberg Merge node at the execution layer.
