hi, we are designing a heavy duty database in pgsql that expects to grow at an average of 100 MB spread over tables of 250 tables. We require always on database (24 X 7) database. And if one fails, the other one needs to start up. Could you someone tell me if there's any open source project that enables real time replication of data back up. I can use heartbeat, mon etc then to awake the other server if the main server is down. Thanks, Hrishikesh __________________________________________________________ How much free photo storage do you get? Store your friends 'n family snaps for FREE with Yahoo!
