Postgres-R source code release

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.

Regards

Markus Wanner
