I have successfully got a slony cluster started with 3 nodes now. I 
tried adding 4 new nodes and have been getting this error.

ERROR  remoteListenThread_1: db_getLocalNodeId() returned 11 - wrong 
database?

Here is where I have got so far on this, I tested the credentials in the 
DEBUG line of the log for this error (not posted here for security 
reasons), and the host definition was not 'localhost'

I did find that the nodes had the host name assigned to 127.0.0.1, I 
changed that to their primary external IP's in the hosts tables and 
restarted slon on all 4 nodes, but I still get this error. Any ideas?
