Depends what you mean by 'clustered'. We run PostgreSQL in
a HA environment (which some might call a 'cluster') with
2 PostgreSQL servers running their own PostgreSQL instance,
but with the ability to automatically failover to their
partner using Heartbeat (from linux-ha.org)
The data lives on NFS servers and so is available to both
hosts.
Consider this a "poor man's HA cluster", altho it works
reasonably well, and all software elements are free.
Cheers,
CM
