   * pg_dump.c
   *	  pg_dump is a utility for dumping out a postgres database
   *	  into a script file.
   *
   * Portions Copyright (c) 1996-2017, PostgreSQL Global Development Group
   * Portions Copyright (c) 1994, Regents of the University of California
   *
   *	pg_dump will read the system catalogs in a database and dump out a
   *	script that reproduces the schema in terms of SQL that is understood
   *	by PostgreSQL
   *
   *	Note that pg_dump runs in a transaction-snapshot mode transaction,
   *	so it sees a consistent snapshot of the database including system
   *	catalogs. However, it relies in part on various specialized backend
   *	functions like pg_get_indexdef(), and those things tend to look at
   *	the currently committed state.  So it is possible to get 'cache
   *	lookup failed' error if someone performs DDL changes while a dump is
   *	happening. The window for this sort of thing is from the acquisition
   *	of the transaction snapshot to getSchemaData() (when pg_dump acquires
   *	AccessShareLock on every table it intends to dump). It isn't very large,
   *	but it can happen.
   *

  		 * THROTTLE:

  		 * slowing down pg_dump when backing up large tables. Users with both
  		 * slow & fast (multi-processor) machines experienced performance
  		 * degradation when doing a backup.
  		 *
  		 * Initial attempts based on sleeping for a number of ms for each ms
  		 * of work were deemed too complex, then a simple 'sleep in each loop'
  		 * implementation was suggested. The latter failed because the loop
  		 * was too tight. Finally, the following was implemented:
  		 *
  		 * If throttle is non-zero, then
  		 *		See how long since the last sleep.
  		 *		Work out how long to sleep (based on ratio).
  		 *		If sleep is more than 100ms, then
  		 *			sleep
  		 *			reset timer
  		 *		EndIf
  		 * EndIf
  		 *
  		 * where the throttle value was the number of ms to sleep per ms of
  		 * work. The calculation was done in each loop.
  		 *
  		 * Most of the hard work is done in the backend, and this solution
  		 * still did not work particularly well: on slow machines, the ratio
  		 * was 50:1, and on medium paced machines, 1:1, and on fast
  		 * multi-processor machines, it had little or no effect, for reasons
  		 * that were unclear.
  		 *
  		 * Further discussion ensued, and the proposal was dropped.
  		 *
  		 * For those people who want this feature, it can be implemented using
  		 * gettimeofday in each loop, calculating the time since last sleep,
  		 * multiplying that by the sleep ratio, then if the result is more
  		 * than a preset 'minimum sleep time' (say 100ms), call the 'select'
  		 * function to sleep for a subsecond period ie.
  		 *
  		 * select(0, NULL, NULL, NULL, &tvi);
  		 *
  		 * This will return after the interval specified in the structure tvi.
  		 * Finally, call gettimeofday again to save the 'last sleep time'.

   * BuildArchiveDependencies - create dependency data for archive TOC entries
   *
   * The raw dependency data obtained by getDependencies() is not terribly
   * useful in an archive dump, because in many cases there are dependency
   * chains linking through objects that don't appear explicitly in the dump.
   * For example, a view will depend on its _RETURN rule while the _RETURN rule
   * will depend on other objects --- but the rule will not appear as a separate
   * object in the dump.  We need to adjust the view's dependencies to include
   * whatever the rule depends on that is included in the dump.
   *
   * Just to make things more complicated, there are also "special" dependencies
   * such as the dependency of a TABLE DATA item on its TABLE, which we must
   * not rearrange because pg_restore knows that TABLE DATA only depends on
   * its table.  In these cases we must leave the dependencies strictly as-is
   * even if they refer to not-to-be-dumped objects.
   *
   * To handle this, the convention is that "special" dependencies are created
   * during ArchiveEntry calls, and an archive TOC item that has any such
   * entries will not be touched here.  Otherwise, we recursively search the
   * DumpableObject data structures to build the correct dependencies for each
   * archive TOC item.
