25  * The "eflags" argument to ExecutorStart and the various ExecInitNode
26  * routines is a bitwise OR of the following flag bits, which tell the
27  * called plan node what to expect. Note that the flags will get modified
28  * as they are passed down the plan tree, since an upper node may require
29  * functionality in its subnode not demanded of the plan as a whole
30  * (example: MergeJoin requires mark/restore capability in its inner input),
31  * or an upper node may shield its input from some functionality requirement
32  * (example: Materialize shields its input from needing to do backward scan).
33  *
34  * EXPLAIN_ONLY indicates that the plan tree is being initialized just so
35  * EXPLAIN can print it out; it will not be run. Hence, no side-effects
36  * of startup should occur. However, error checks (such as permission checks)
37  * should be performed.
38  *
39  * EXPLAIN_GENERIC can only be used together with EXPLAIN_ONLY. It indicates
40  * that a generic plan is being shown using EXPLAIN (GENERIC_PLAN), which
41  * means that missing parameter values must be tolerated. Currently, the only
42  * effect is to suppress execution-time partition pruning.
43  *
44  * REWIND indicates that the plan node should try to efficiently support
45  * rescans without parameter changes. (Nodes must support ExecReScan calls
46  * in any case, but if this flag was not given, they are at liberty to do it
47  * through complete recalculation. Note that a parameter change forces a
48  * full recalculation in any case.)
49  *
50  * BACKWARD indicates that the plan node must respect the es_direction flag.
51  * When this is not passed, the plan node will only be run forwards.
52  *
53  * MARK indicates that the plan node must support Mark/Restore calls.
54  * When this is not passed, no Mark/Restore will occur.
55  *
56  * SKIP_TRIGGERS tells ExecutorStart/ExecutorFinish to skip calling
57  * AfterTriggerBeginQuery/AfterTriggerEndQuery. This does not necessarily
58  * mean that the plan can't queue any AFTER triggers; just that the caller
59  * is responsible for there being a trigger context for them to be queued in.
60  *
61  * WITH_NO_DATA indicates that we are performing REFRESH MATERIALIZED VIEW
62  * ... WITH NO DATA. Currently, the only effect is to suppress errors about
63  * scanning unpopulated materialized views.
