Hi,
 I´m relatively new to slony and I needed help to configure it in order 
to satisfy the following conditions:
I have four nodes, 1-4, and two replication sets, A-B. B is a subset of 
A. Node 1 is the master and node 2 subscribes to 1 to replicate set A. 
Nodes 3 and 4 both subscribe to node 2 but i don´t need them to 
replicate all of the tables in set A, only the ones in the subset B.
Am I supposed to create set B with node 1 as origin and only subscribe 
nodes 3 and 4 to set B in node 2?. To do this, is it necessary to also 
subscribe node 2 to 1 to replicate set B when set A already includes the 
tables in set B?.
Thanks in advance.
Damian.
