We have a relatively simple setup.

One master; three slaves. All boxes on Debian linux (testing) running  
postgresql 8.2.3 and slony 1.2.6, both compiled from source.

2 problems:

1) After compiling Slony 1.2.7 on all four boxes, the UPDATE  
FUNCTIONS call failed on the master box failed. I'm afraid I was  
stupid, and didn't save the error message -- but I believe it was  
complaining about not finding a function in my replication cluster.  
Has anyone else had problems upgrading from 1.2.6 to 1.2.7? If not,  
I'll try again later and if it throws up an error again, I'll be more  
diligent and record it and report here.

2) How soon will Slony be officially sanctioned for 8.2.x? We  
upgraded our servers without realizing it might cause problems with  
Slony; so far, all seems to be working, but should I be concerned?

TIA for any help.
