Well, clustering is just a general term for putting several things, say, computers, together to a common cause. If you cluster a database system, you need some way to distribute the incoming requests across the machines, which you can either do on the network layer or on the application layer. Sequoia does the latter. But I don't see any "broadcasting" in there as a defining quality. -- Peter Eisentraut http://developer.postgresql.org/~petere/ ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
