If you had several standbys, you could distribute the work of the pg_dump among them. This would be a huge speedup for a large database, potentially, thanks to parallelization of I/O and network. Imagine doing a pg_dump of a 300GB database in 10min. -- -- Josh Berkus PostgreSQL Experts Inc. http://www.pgexperts.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
