The main PostgreSQL compatible software that's good at this role is
Bucardo: http://bucardo.org/
It allows having multiple masters, so each of your disconnected nodes
would each be one. And then when they reconnect, they asynchronously
replicate back to the big master. The exact way in which conflict
resolution is done is something you can provide a handler for. So it
handles most of the dirty work of figuring out what's changed via
triggers, and you just plug in the application logic that makes sense
for you in order to resolve any conflicts.
You are correct that the built-in replication features in 9.0, and most
of PostgreSQL replication software, it not really suitable for your
situation. Bucardo probably is.
