Hello

pgpool does a great job at that. pgpool does load balancing to the first 
statement that is considered a write statement, for that point on, the 
rest of the transaction is routed to the primary.

But the question here is how to achieve all of the aforementioned 
features, of all those great tools combined, or ideally combined in one.
