yeah, actually, i have not been successful to set up this, but let me 
give some information for you.
1. download the postgresql snapshot source code from here:
http://www.postgresql.org/ftp/snapshot/dev/
(this is a daily tarball)

2. Get the corresponding patch for postgres-r from:
http://www.postgres-r.org/downloads/

3. apply the patch for snapshot source, and configure like this:

./configure --enable-replication
make & make install

4. install the GCS ensemble, according the document : 
http://www.cs.technion.ac.il/dsl/projects/Ensemble/doc.html

5. start ensemble daemon and gossip if neccessary ( yes, make sure the 
two nodes can 'GCS' each other)

3. Assume that you have two nodes, start up postgresql and create a 
database 'db', and create a table 'tb' for testing which should be have 
a primary key for all nodes.

4. At the origin node, execute the command at psql console:
alter database db start replication in group gcs;
(which means the database 'db' is the origin and the group 'gcs' is the 
GCS group name)

5. At the subscriber node, execute the command:
alter database db accept replication from group gcs;


Hope information above would be helpful, and keep in touch.
