* IDEA: Multi-master replication possible through spread (or even master-slave)...

Has anyone here thought about using the spread libraries for WAL
replication amongst mutliple hosts? With this library I think it'd be
possible to have a multi-master replication system...
http://www.spread.org/
I'm not familiar enough with the guts of postgres to be able to
impliment this (yet), but thought that it might be something for someone
else to look into. At the very least, check out the libs, they're very
impressive and I've had good luck with them in the past. If push comes
to shove, in a few months I may write a few ruby+spread utils to do
this, but we'll see... -sc

Yes, there is some work being done to use Spread as the group
communication system
for Postgres-R, but we are just getting started with this software.
Using a group
communication system to establish total order messages is one of the
basic principles for
synchronous multi-master replication with Postgres-R. Currently
Ensemble (form Cornell
University) is used, but Spread looks to be more robust and it appears
to be supported
on most if not all of the PostgreSQL supported platforms.
It's very cool to see positive testimony for Spread, and I hope I will
feel the same way
as I become more familiar with it.

Howdy. Darren, I'd reply in person, but there are issues with
your mail account. ;~) At anyrate, is there a mailing list that the
Postgres-R development is happening on so that I could drop in and
either listen/contribute? Thanks. -sc

Sure. The mailing list is
http://www.greatbridge.org/mailman/listinfo/pgreplication-general
It's not only for Postgres-R, but any PostgreSQL
replication ideas, discussions, or projects.
Feel free to listen or contribute.
Darren
BTW: My apologies for the email issues. Should be fixed now.
