Going off at a bit of a tangent here.. OpenCloud does telco 
infrastructure software and we package postgresql with our product to do 
persistence of long-lived state (deployed services, cluster 
configuration, customer provisioning data etc). The statement caching 
stuff is not really an issue either way for what we do, since we already 
intelligently reuse statements in our persistance layer.

One thing we've found is that our customers don't really care about 
database setup for this sort of use, they want it to "just work". In 
fact we package Derby instead of PostgreSQL with our development 
versions just so there's one less thing for the developer to set up. So 
even if we cared about statement caching it wouldn't really matter if it 
was together with the driver or a separate package as we'd still end up 
doing all the packaging together with the application and testing of the 
combined product.

While what we do is essentially an appserver (JAIN SLEE) I suspect the 
same applies to standalone java telco apps, you're going to be doing DB 
integration as part of your app not as something that gets plugged in 
afterwards, so I'm not sure how relevant having it in the standard 
driver is.
