The idea: We are looking for a way to implement a synchronous single-master / multiple slaves systems.
Meanwhile we are able to serialize / deserialize WAL records and send them to a group communication system which transports those records to the slave database.
This is not hard to do.
In fact, I believe Command Prompt's Mammoth Replicator does exactly this.
Very close. We don't use the WAL (yet, slated for probably 8.1) but we
do use a transaction log shipping method. So the implementation is almost the same.

Joshua,
This sounds interesting. If you don't use the WAL but a transaction log shipping - what does it mean in terms of PostgreSQL? Do you create your own transaction log?
What really interests me here: Where is you code located in order to make sure that this things can work reliably?
Best regards,
Hans
