Yes, replication is going to be the next BIG thing in the database world.
Right now, no one (not even Oracle, and I've experience with their system)
has a good solution out there. The stuff that pgreplication is doing is
earth-shatteringly huge. Read through the research paper and see for yourself
what I mean.

What the original poster is looking for is called "peer-to-peer eager
replication". "peer-to-peer" because there is no master server, "eager"
because the two databases are always exactly the same.
The really cool thing about pgreplication will be that it is hot-swappable. If
one of the servers goes down, the whole thing will still work. You can also
add databases to the system on-the-fly. That way, you can always keep one (or
two or three) extra stand-by databases.
