Note that the flags will get modified * as they are passed down the plan tree, since an upper node may require * functionality in its subnode not demanded of the plan as a whole * (example: MergeJoin requires mark/restore capability in its inner input), * or an upper node may shield its input from some functionality requirement * (example: Materialize shields its input from needing to do backward scan). * * EXPLAIN_ONLY indicates that the plan tree is being initialized just so * EXPLAIN can print it out; it will not be run. Hence, no side-effects * of startup should occur. However, error checks (such as permission checks) * should be performed. * * REWIND indicates that the plan node should try to efficiently support * rescans without parameter changes. (Nodes must support ExecReScan calls * in any case, but if this flag was not given, they are at liberty to do it * through complete recalculation. Note that a parameter change forces a * full recalculation in any case.) * * BACKWARD indicates that the plan node must respect the es_direction flag. * When this is not passed, the plan node will only be run forwards. * * MARK indicates that the plan node must support Mark/Restore calls. * When this is not passed, no Mark/Restore will occur. * * SKIP_TRIGGERS tells ExecutorStart/ExecutorFinish to skip calling * AfterTriggerBeginQuery/AfterTriggerEndQuery. This does not necessarily * mean that the plan can't queue any AFTER triggers; just that the caller * is responsible for there being a trigger context for them to be queued in. */ #define EXEC_FLAG_EXPLAIN_ONLY 0x0001 /* EXPLAIN, no ANALYZE */ #define EXEC_FLAG_REWIND 0x0002 /* need efficient rescan */ #define EXEC_FLAG_BACKWARD 0x0004 /* need backward scan */ #define EXEC_FLAG_MARK 0x0008 /* need mark/restore */ #define EXEC_FLAG_SKIP_TRIGGERS 0x0010 /* skip AfterTrigger calls */ #define EXEC_FLAG_WITH_NO_DATA 0x0020 /* rel scannability doesn't matter */ /* Hook for plugins to get control in ExecutorStart() */ typedef void (*ExecutorStart_hook_type) (QueryDesc *queryDesc, int eflags);
