Wow. First, thanks again for all your efforts, Jan. Second, I'm disappointed to hear the slony author and lead developer is leaving the slony leadership. When is that going to happen? And what does that mean with respect to your future involvement in slony?
It means that I will try to do with Slony-I what I have done successfully with several other PostgreSQL related projects - to make sure the project doesn't depend on me in person any more. None of the big items I've done (rewrite rule system, PL/pgSQL, PL/Tcl, TOAST, NUMERIC, foreign keys) really requires my attention if there's a bug. I was able to do the conceptual work and important parts of the implementation, but I didn't get stuck in/with the maintenance. I constider this a very important aspect of being a CORE developer.
What I am trying to do is to spend less and less time on Slony-I and more and more time on Slony-II - the synchronous multi-master system. Slony-I was for sure one of the better things that I've done so far, but it's not going to allow early retirement with financial independance and wealth. And as long as Afilias is using Slony-I in production, Andrew Sullivan will not let me do whatever I want if there's a severe problem nobody else can fix.
So don't worry, I'll be around.

the Slony-I team has produced a great product, but the project management (that's mostly me here) sucks big time!
Shortly after giving Chris Browne green light for the 1.0.4 announcement we found a way to guard against bug #896. That being a really bad one I decided to stop the 1.0.4 release and go for 1.0.5 including that fix. But I failed to make sure Chris, Justin and others involved in the announcement process get the message.
I have just committed those changes and 1.0.5 should be available later today.
I apologize for the confusion and look forward to retire from the Slony-I project leadership position in order to fully focus on the multimaster replication project Afilias has decided to put forward.
