Обсуждение: pgsql: Forbid SJE with result relation
Forbid SJE with result relation The target relation for INSERT/UPDATE/DELETE/MERGE has a different behavior than other relations in EvalPlanQual() and RETURNING clause. This is why we forbid target relation to be either source or target relation in SJE. It's not clear if we could ever support this.
