I have a simple question, how do I know that my master->slave (only 1) slony system is working?  Is there a query I 
can execute?

Also, I didn't see any upgrade instructions for 1.01 to 1.02 (or 1.03 when its available). Is it as simple as 
compiling the programs, stopping/starting slon?

Also, while I am at it.  Is there a query to see which version of slony I am using.  I currently have 2 system on 
1.01, but I am planning on many more and a query would also help here.

Thanks
Jim
