Hi!

That's not real clustering, it's replication. As far as I understand, "real" clustering does not require a master server, and allows write-operations on any of the cluster nodes. Unfortunately, PgSQL still does not support real clustering. Of course, this may not be a real issue for many usages, but if your app starts to grow in clients, it may be a bottleneck at a point of time.

there's a very nice JDBC-based solution for this: <https:// forge.continuent.org/projects/sequoia/> I looked into using it when it was still named C-JDBC, but in the end we never required the features. If all DB-access is passing via JDBC, this is a very elegant solution that is backend-agnostic and allows for real redundancy w/o any SPOF.

cheers

Postgresql has various clustering options: SLony, pgpool, etc. They don't believe in a one size fits all solution.
