- Added --create, --no-owner, --superuser, --no-reconnect (pg_dump & pg_restore)
- Added code to dump 'Create Schema' statement (pg_dump) - Don't bother to disable/enable triggers if we don't have a superuser (pg_restore) - Cleaned up code for reconnecting to database. - Force a reconnect as superuser before enabling/disabling triggers. - Added & Removed --throttle (pg_dump) - Fixed minor bug in language dumping code: expbuffres were not being reset. - Fixed version number initialization in _allocAH (pg_backup_archiver.c) - Added second connection when restoring BLOBs to allow temp. table to survive (db reconnection causes temp tables to be lost).

* If throttle is non-zero, then
|
||||
* See how long since the last sleep.
|
||||
* Work out how long to sleep (based on ratio).

|

* 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. Fianally, call
|
||||
* gettimeofday again to save the 'last sleep time'.
