- Param *param = (Param *) node; + if (list_member_int(context->safe_param_ids, ((Param *) node)->paramid)) + return false; - if (param->paramkind != PARAM_EXEC || - !list_member_int(context->safe_param_ids, param->paramid)) - { - if (max_parallel_hazard_test(PROPARALLEL_RESTRICTED, context)) - return true; - } - return false; /* nothing to recurse to */ + if (max_parallel_hazard_test(PROPARALLEL_RESTRICTED, context)) + return true; I think your revised logic is wrong here because it drops the paramkind test, and I don't see any justification for that. IIUC, param IDs are tracked separately for extern and exec parameters, so why would we ignore that distinction here? But I'm also wondering if we're missing a trick here, because isn't a PARAM_EXTERN parameter always safe, given SerializeParamList? If so, this || ought to be &&, but if that adjustment is needed, it seems like a separate patch. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
