Hi All Thanks for your reply . Actually, I have a cluster setup with two nodes in it. I am having postgres-8.1.2 and am using slony-1.1.5 for replication between two nodes in that cluster. Now, If I plan to upgrade both the servers to postgres-8.1.21, I will be doing it one by one . When one system is upgraded to postgres-8.1.21 , other will still be on postgres-8.1.2 until its also upgraded. So I was just wondering if there wont be any issue with replication using slony-1.1.5 from postgres-8.1.2 to postgres-8.1.21 . Second question : Will slony 1.1.5 work with postgres-8.1.21 or I'll have to upgrade slony as well. Is there any compatibility matrix between slony and postgres . where can I find that ?? Please Reply ... Thanks...

I'm not doing it, wanting to stay on a bug > ridden release by applying a single patch is insane. Not only that, but the to upgrade to 8.1.21 would require less work (and the same downtime) as to apply the patch.
