Hello Friends,
I'm looking for a free software project which can replicate postgres databases in a runtime environment. I've googled for many such projects but before going further i need your assistance in selecting the best project among all.

* PG Replication
* Postgres-R
* DRAGON: Database Replication based on Group Communication
* The Slony-1 Project
* PGCluster
* DBBalancer
* PostgreSQL Replicator: Tutorial, Paper, Techdocs
* eRServer: Techdocs
* DBMirror: Will be in the 7.3 contrib directory.
* Usogres: Techdocs

Thanks in advance.

Regards,
Turab

Slony-I is the best definitely... And i think it comes built in since version 7.3 or something.

I've also heard that Slony-I is the best freely available one for PostgreSQL.

But if you are using EnterpriseDB edition of Postgres there are other possibilities. If this is the case check here.
