If you have a howto or some documentation on how to get DRBD to work with EC2 (or rackspace) I'd appreciate a link to it. > I've also had success using the native replication to spin read-only slaves > off > those HA masters, using pgpool to load balance selects. I think I am probably going to explore this option first. I don't know why automatic failover, failback, etc are not built in already. I guess even connection pooling ought to be built in. Seems like everybody would need that no? -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
