- *
- * oldrel: source of data (we use the attr_needed, min_attr, max_attr fields)
- * appinfo: supplies parent_relid, child_relid, col_mappings
- * new_min_attr, new_max_attr: desired bounds of new attr_needed array
- *
- * The relid sets are adjusted by substituting child_relid for parent_relid.
- * (NOTE: oldrel is not necessarily the parent_relid relation!) We are also
- * careful to map attribute numbers within the array properly. User
- * attributes have to be mapped through col_mappings, but system attributes
- * and whole-row references always have the same attno.
