OK ... but sorry I may misunderstand something more ... but why Joshua is 
talking about a large cluster ... ? Why the need of several database for one 
application ? 
And how can you maintain one application with several database ?? 
(replication ?, I'm not sure there is a realtime solution of replication with 
PostgreSQL able to accep 10000 insert by second ... for the moment !?)

And second point ... to talk about beowulf cluster .... is there any solution 
for PostgreSQL ? We here talking many time about MySQL solution for that ... 
why PostgreSQL do not have this kind of solution, yet ?
