+ *
+ * dest.h
+ * support for communication destinations
+ *
+ * Whenever the backend executes a query that returns tuples, the results
+ * have to go someplace. For example:
+ *
+ * - stdout is the destination only when we are running a
+ * standalone backend (no postmaster) and are returning results
+ * back to an interactive user.
+ *
+ * - a remote process is the destination when we are
+ * running a backend with a frontend and the frontend executes
+ * PQexec() or PQfn(). In this case, the results are sent
+ * to the frontend via the functions in backend/libpq.
+ *
+ * - DestNone is the destination when the system executes
+ * a query internally. The results are discarded.
+ *
+ * dest.c defines three functions that implement destination management:
+ *
+ * BeginCommand: initialize the destination at start of command.
+ * CreateDestReceiver: return a pointer to a struct of destination-specific
+ * receiver functions.
+ * EndCommand: clean up the destination at end of command.
+ *
+ * BeginCommand/EndCommand are executed once per received SQL query.
+ *
+ * CreateDestReceiver returns a receiver object appropriate to the specified
+ * destination. The executor, as well as utility statements that can return
+ * tuples, are passed the resulting DestReceiver* pointer. Each executor run
+ * or utility execution calls the receiver's rStartup method, then the
+ * receiveSlot method (zero or more times), then the rShutdown method.
+ * The same receiver object may be re-used multiple times; eventually it is
+ * destroyed by calling its rDestroy method.
+ *
+ * In some cases, receiver objects require additional parameters that must
+ * be passed to them after calling CreateDestReceiver. Since the set of
+ * parameters varies for different receiver types, this is not handled by
+ * this module, but by direct calls from the calling code to receiver type
+ * specific functions.
+ *
+ * The DestReceiver object returned by CreateDestReceiver may be a statically
+ * allocated object (for destination types that require no local state),
+ * in which case rDestroy is a no-op. Alternatively it can be a palloc'd
+ * object that has DestReceiver as its first field and contains additional
+ * fields (see printtup.c for an example). These additional fields are then
+ * accessible to the DestReceiver functions by casting the DestReceiver*
+ * pointer passed to them. The palloc'd object is pfree'd by the rDestroy
+ * method. Note that the caller of CreateDestReceiver should take care to
+ * do so in a memory context that is long-lived enough for the receiver
+ * object not to disappear while still needed.
+ *
+ * Special provision: None_Receiver is a permanently available receiver
+ * object for the DestNone destination. This avoids useless creation/destroy
+ * calls in portal and cursor manipulations.
