It is not ready yet.
You can find it at ...
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 :).
