This scenario would be supported by Slony-I; there are several ways to
accomplish it, probably the easiest being thus...

- Create two nodes, 1 and 2

- Create two replication sets - #1 and #2.

- Set 1 has origin of node 1
- Set 2 has origin of node 2

- Add tablea to set 1
- Add tableb to set 2

- Subscribe node 2 to set 1
- Subscribe node 1 to set 2

Either node can run PG 7.4 or 8.0...
