I know there are some tools, but : * bucardo -> not for failover * pg_cluster -> frozen, currently unavailable, old ..?!? Perhaps we should have a look at * pg_pool(II) * clustering solution from Cybertec, called "cybercluster" We want to implement it on 2 servers with identical hardware -> shared nothing architecture. One of them contains the production database already. any help appreciated...GERD...
