Oh wow, I don't agree with that at all. People may name the parameters for documentation purposes, and then have things like WHERE foo = $1, foo happening also to be the name associated with $1. Boom! In any case, I think this is 9.2 material. We need to get a beta out the door, and I emphatically think we should be focusing on resolving the issues with features already committed, not committing new ones. ...Robert
