 *
 *	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:
		 *
		 * There was considerable discussion in late July, 2000 regarding
		 * 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'.

 * plus catalog ID and subid which are the lookup key for pg_description,
 * plus the dump ID for the object (for setting a dependency).
