Ben,
As far as I can see MusicBrainz only does one way replication (which I already
achieved).
Two ways replication (without re-sending the information you have just
received) is a bit more complex.
I could not find much info on the MusicBrainz project anyway.
Thanks,

Objet : Re: [GENERAL] Very asynchrnous replication system
The MusicBrainz project replicates in a way that sounds like it could fit your
needs. It depends on a lot of perl, but if that's not a showstopper, then maybe
adapting their replication scheme would work for you.

Hello,
I must replicate (or synchronise) data between disconnected postgreSQL
databases ... hence a replication "very asynchronous"!
Application description
This an application to manage sales forces with a central application (and
postgreSQL server) where everybody in the office can connect (this a web
application: Tomcat with Spring 2+ Struts 2 + iBatis + PostgreSQL).
But there are also "little itinerant applications": the sales rep have the
application on their laptop and a PosgreSQL server with a copy of the data
(they are interested in ) from the main server database.
From time to time, the sales reps connect to the internet and request a data
synchronisation: they send their modification and receive the headquarters
modification.
(no problem about data overlap: the data owner is clearly identified by the
application framework)
My problem:
Does such an existing system (the replication one) exist ?
I search the web I did not find anything !
I have started to do something (with triggers, log table and table export -
using DDL-Utils) ... but looking at the spreadth of the task layed out in front
of me, I am thinking that I will be better off using or adapting an existing
replication system
Have fun,
