   4  *        pg_dump is a utility for dumping out a postgres database
   5  *        into a script file.
   6  *
   7  * Portions Copyright (c) 1996-2012, PostgreSQL Global Development Group
   8  * Portions Copyright (c) 1994, Regents of the University of California
   9  *
  10  *      pg_dump will read the system catalogs in a database and dump out a
  11  *      script that reproduces the schema in terms of SQL that is understood
  12  *      by PostgreSQL
  13  *
  14  *      Note that pg_dump runs in a transaction-snapshot mode transaction,
  15  *      so it sees a consistent snapshot of the database including system
  16  *      catalogs. However, it relies in part on various specialized backend
  17  *      functions like pg_get_indexdef(), and those things tend to run on
  18  *      SnapshotNow time, ie they look at the currently committed state.  So
  19  *      it is possible to get 'cache lookup failed' error if someone
  20  *      performs DDL changes while a dump is happening. The window for this
  21  *      sort of thing is from the acquisition of the transaction snapshot to
  22  *      getSchemaData() (when pg_dump acquires AccessShareLock on every
  23  *      table it intends to dump). It isn't very large, but it can happen.

1317                  *
1318                  * There was considerable discussion in late July, 2000 regarding
1319                  * slowing down pg_dump when backing up large tables. Users with both
1320                  * slow & fast (multi-processor) machines experienced performance
1321                  * degradation when doing a backup.
1322                  *
1323                  * Initial attempts based on sleeping for a number of ms for each ms
1324                  * of work were deemed too complex, then a simple 'sleep in each loop'
1325                  * implementation was suggested. The latter failed because the loop
1326                  * was too tight. Finally, the following was implemented:
1327                  *
1328                  * If throttle is non-zero, then
1329                  *              See how long since the last sleep.
1330                  *              Work out how long to sleep (based on ratio).
1331                  *              If sleep is more than 100ms, then
1332                  *                      sleep
1333                  *                      reset timer
1334                  *              EndIf
1335                  * EndIf
1336                  *
1337                  * where the throttle value was the number of ms to sleep per ms of
1338                  * work. The calculation was done in each loop.
1339                  *
1340                  * Most of the hard work is done in the backend, and this solution
1341                  * still did not work particularly well: on slow machines, the ratio
1342                  * was 50:1, and on medium paced machines, 1:1, and on fast
1343                  * multi-processor machines, it had little or no effect, for reasons
1344                  * that were unclear.
1345                  *
1346                  * Further discussion ensued, and the proposal was dropped.
1347                  *
1348                  * For those people who want this feature, it can be implemented using
1349                  * gettimeofday in each loop, calculating the time since last sleep,
1350                  * multiplying that by the sleep ratio, then if the result is more
1351                  * than a preset 'minimum sleep time' (say 100ms), call the 'select'
1352                  * function to sleep for a subsecond period ie.
1353                  *
1354                  * select(0, NULL, NULL, NULL, &tvi);
1355                  *
1356                  * This will return after the interval specified in the structure tvi.
1357                  * Finally, call gettimeofday again to save the 'last sleep time'.
