Replication Multi Master Asyncronous - Mailing list pgsql-admin

Hi..
I success develop a Replication Multi Master Async through PHP.
Just few step to make replication with php, but I want to make this replication can embedded into PostgreSQL.

This step by step .
Make every record unique in every
  Every table that create must added by 1 Field ( ex : clusterid ).
  Every primary key must changed to add clusterid.
  Every update ( insert and update ) must corelation with clusterid.
Make Update / Insert to Log
Send Log to another member cluster.
Every member cluster Execute Log that receive.
Send message that to Sender.
Delete log.

That's model that I want to make code .
