you are describing usenet. (it was not designed for relational database

Reliability, Availability and Scalability
Mirroring the data on multiple nodes enhances reliability of the
database system. As Postgres-R is using a group communication system
it is easily possible to add or remove nodes on the running system.
Crashing nodes are automatically detected and removed, thus do not
affect the operating of the database system. This facilitates
administration tasks and ensures greater availability and scalability
of the database system.

I think some disclosure is in order about postgres-r:
"Please note that this is *experimental* software. primarily released
for review by developers familiar with Postgres."
Looks interesting though...
