+ * The "eflags" argument to ExecutorStart and the various ExecInitNode
+ * routines is a bitwise OR of the following flag bits, which tell the
+ * called plan node what to expect.  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.
