Dear Hackers, it has been two years, since I've presented my work on Postgres-R for the first time to a broader audience in Toronto. I continued maintaining that code in my spare time, but to be honest, I didn't have much time for it. As much as I'd like to change that, I now think the best thing for the project itself is to open it up and release the source code. I'd very much like to get others aboard and turn Postgres-R into a real community project again. Of course, the recent core statement about wanting an integrated replication solution also influenced my decision, even though I realize that Postgres-R is way more ambitious path than a log shipping solution. As a first step towards a community project, I've cleaned up the code and tried to comment and document it as good as I can. You are welcome to download the latest patch from http://www.postgres-r.org/downloads/. It expects to be applied against today's CVS HEAD. You'll find a README and a pretty exhaustive TODO file under src/backend/replication/. I plan to write a series of more technical mails following this one, to start the discussion about the internals of Postgres-R and decisions I made. That should give some starting points for those interested it the project. In case you are wondering: I've got married and I'm glad to tell you that I changed my very German sounding name Schiltknecht to a more pronounceable one: my new surname is Wanner. Looking forward to inspiring discussions with fellow hackers.
