Hi all,

I am going to be upgrading slony cluster from 1.2.20 to 1.2.21 here 
soon, however before doing it I have some concerns.

My cluster is a simple master to slave, however my slave daemon is 
writing out to archive files, which I am shipping to dozens of other 
nodes via log shipping. I've got the process down and tested it on some 
test boxes to upgrade and that works fine, however I'm wondering if the 
upgrade will cause the remote nodes to suddenly not be able to apply the 
archive logs being shipped to them. I am hoping that since this is a 
minor upgrade (20 -> 21), I would be surprised if this upgrade made any 
major modifications such as this, but I want to be sure.

 I don't think the remote nodes even have slony installed, they just 
have a dump of the slave database from when the nodes were set up from a 
modified version of the slon1_dump.sh file, which I believe is setting 
up the schema and environment they need (such as the _slony schema and 
functions). However I could be wrong on this.

So long story short, upgrading from 1.2.20 to 1.2.21, will I need to 
push any updates to my remote boxes that are not part of the actual 
cluster, but just feeding off the archive logs created.

Thanks in advance,
