23  * The "eflags" argument to ExecutorStart and the various ExecInitNode
24  * routines is a bitwise OR of the following flag bits, which tell the
25  * called plan node what to expect. Note that the flags will get modified
26  * as they are passed down the plan tree, since an upper node may require
27  * functionality in its subnode not demanded of the plan as a whole
28  * (example: MergeJoin requires mark/restore capability in its inner input),
29  * or an upper node may shield its input from some functionality requirement
30  * (example: Materialize shields its input from needing to do backward scan).
31  *
32  * EXPLAIN_ONLY indicates that the plan tree is being initialized just so
33  * EXPLAIN can print it out; it will not be run. Hence, no side-effects
34  * of startup should occur. However, error checks (such as permission checks)
35  * should be performed.
36  *
37  * REWIND indicates that the plan node should try to efficiently support
38  * rescans without parameter changes. (Nodes must support ExecReScan calls
39  * in any case, but if this flag was not given, they are at liberty to do it
40  * through complete recalculation. Note that a parameter change forces a
41  * full recalculation in any case.)
42  *
43  * BACKWARD indicates that the plan node must respect the es_direction flag.
44  * When this is not passed, the plan node will only be run forwards.
45  *
46  * MARK indicates that the plan node must support Mark/Restore calls.
47  * When this is not passed, no Mark/Restore will occur.
48  *
49  * SKIP_TRIGGERS tells ExecutorStart/ExecutorFinish to skip calling
50  * AfterTriggerBeginQuery/AfterTriggerEndQuery. This does not necessarily
51  * mean that the plan can't queue any AFTER triggers; just that the caller
52  * is responsible for there being a trigger context for them to be queued in.
53  *
54  * WITH/WITHOUT_OIDS tell the executor to emit tuples with or without space
55  * for OIDs, respectively. These are currently used only for CREATE TABLE AS.
56  * If neither is set, the plan may or may not produce tuples including OIDs.
