Maybe some people haven't read this site here:
http://www.postgresqldocs.org/wiki/Replication,_Clustering,_and_Connection_Pooling
It gives a nice overview. Another interesting project which isn't
production ready yet is Postgres-R (http://www.postgres-r.org/)

I hoped that it would be easier to get the nodes back in sync
but it seems that all Postgres Multi-Master solutions are not
reliable at the moment. I've planed to test CyberCluster
this weekend but I already suspected that this rsync solutions
have some shortcomings. Sniff...
It seems that we have to wait for PGCluster-II which isn't a
"shared nothing" solution. Instead all files are on a shared
medium like SAN or iSCSI and all instances uses this medium
(similar to Oracle).

I've been testing Cybercluster (which is a modified PgCluster) ... I
have two back-end databases, one load balancer, and one replicator.
I've been testing failover and rebuilding a degraded cluster, and I'm
finidng that it is REALLY easy for the two back-ends to get out of
sync with each other. This is very disturbing. I was wondering if
anyone has experience with solving this problem.
