- 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.
