try to write prototype and show advantages. I am able to undestand
advantages of persistent prep. stamenents, but I see some disadvatage
too. Mainly you have to manage some shared memory space for stored
plans. It's not easy task - MySQL develepoers can talk. Implemenation
on postgresql is little bit dificult - lot of structures that lives in
processed memory have to be moved to shared memory.

This feature is nice, but question is - who do write it? Actually this
problem is solved from outside - with pooling.
