Technically node (or database). That tutorial was written using a single 
server which is stated at the beginning so there is no master or slave 
server.

Check the slony docs for more info on paths, but essentially you need 
paths on each node pointing to every other node it might talk to. So in 
the example given, the master has paths to both slaves, and each slave 
has a path to the master. If you restructure the cluster, and make a 
slave the master, you will need to add a path on that node to the 
remaining slave, and on the remaining slave to the new master.
