Обсуждение: PostgreSQL on cluster

Hello All,

Does anybody have a live cluster with 2 or more computers running
PostgreSQL, connected to single database on shared storage or to
replicated database with load balancing between them?

No, because you can't share the same database files between two
independent servers. You could run PG on a cluster if it could
distribute shared memory, but without specialised hardware it would be
very slow.

Replication is fine, although load-balancing needs to be thought
through. There's been plenty of discussion of this recently, search the
archives for "cluster" or "replication" or "slony".
