Replication Options. - Mailing list pgsql-admin

Hi ,

    I need to implement the following the replication scenario in
postgres database. Here are the details of what we are looking to
implement.

Lets say I have 2 nodes Node1(US) and Node2(Canada),

Node1: tableA , tableB
Node2: tableB , tableA

tableA in Node1 is the master and it should replicate only to slave
tableA in Node2

tableB in Node2 is the master and it should replicate only to slave
tableB in Node1

Can this be possible with any of the replication models available for
Postgres 7.4/8.0 ?

Thanks!
