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".
