Hum?

PostgreSQL doesn't yet have anything meaningful in terms of answers
for multimaster replication, but that represents a tough problem. 
(Albeit one where efforts are under way.

There have historically been several ways of doing single-master
replication, notably including:
- eRServer <http://gborg.postgresql.org/project/erserver/projdisplay.php>
- Mammoth Replicator
<http://www.commandprompt.com/products/mammothreplicator/?page=products&item=mammothpostgresql>
- Slony-I <http://slony.info/>
