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,
