isForCTAS is getting set before pg_plan_query() which is being used in cost_gather(). We will not have a Gather node by then and hence will not pass queryDesc to IsParallelInsertInCTASAllowed(into, NULL) while setting isForCTAS to true. Intention to check query_level == 1 in cost_gather is to consider for only top level query not for other sub queries. With Regards, Bharath Rupireddy. EnterpriseDB: http://www.enterprisedb.com
