Yes, this is the right thing to do although we may not enable parallelism for any more queries by adding "|| !es->lazyEval". Because SELECT are always marked as es->lazyEval=true(And so far we have parallelism only for select). But here we calling the parameter to ExecutorRun as execute_once so !fcache->returnsSet || !es->lazyEval is the correct one and future proof. -- Regards, Dilip Kumar EnterpriseDB: http://www.enterprisedb.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
