It is not ready yet.
You can find it at ...
http://snaga.org/pgsql/
It is based on 7.3
* the 2-phase commit protocol (precommit and commit) * the multi-master replication using 2PC * distributed
transaction(distributed query)
current work
* restarting (from 2nd phase) when the session is disconnected in
2nd phase (XLOG stuffs) * XA compliance
future work
* hot failover and recovery in PostgreSQL cluster * data partitioning on different servers
I have compiled it a while ago.
Seems to be pretty nice :).
