The documentation at http://www.slony.info/documentation/slonylistenercosts.html states that
"It is necessary to have sl_listen entries allowing connection from each node to every other node. Most will normally not need to be [used] (sic) very heavily, but it still means that there needs to be n(n-1) paths." I have been running perfectly fine for several months where this is not true. I have a master node A with 4 sets. Node B replicates all 4 sets and there is of course a path between A and B. Node C replicates 2 sets and there is a path between A and C. But there is no path between B and C. As far as I know, this simply means that I will be restricted if I try to do things like FAILOVER or MOVE SET. I'm thinking if I need to do that, I can add the necessary paths at that time. But not having the extra path from B-C all the time saves resources. In any case, the documentation implies that I MUST have the connection, and that does not appear to be the case.
