Message-ID: <E1tjvJX-007Z9J-RU@gemulon.postgresql.org> (raw)
Fix an oversight in cbc127917 to handle MERGE correctly
ExecInitModifyTable() forgot to trim MERGE-related lists to exclude
entries for result relations pruned during initial pruning, so fix
that.
While at it, make the function's use of the pruned resultRelations
list, rather than ModifyTable.resultRelations, more consistent.
