(BTW, maxed out, with 2 U320 adapters and 6 4Gb HBAs, it's only $75000!) Please tell me, though, what's so controversial about saying that CPU and RAM resources are finite? Besides, since pg_dump is single-threaded, backing up a huge database gets impossible. Federating the database allows multiple pg_dumps to simultaneously dump data to multiple tape drives. - -- Ron Johnson, Jr. Jefferson LA USA Is "common sense" really valid? For example, it is "common sense" to white-power racists that whites are superior to blacks, and that those with brown skins are mud people. However, that "common sense" is obviously wrong. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFFi3zlS9HxQb37XmcRAtVjAKDGPu4jHPyTH9EX5sqPbuHs+wKE3gCeLnnx RvSfELtJ7bieg3HVVqB/7Zk= =FQCv -----END PGP SIGNATURE-----
