Title: A few cleanups that looked like they needed to be done.

* cleanup of the PL/pgSQL function to allow the top boundary to be passed in as a parameter. Without it, the top boundary is always what it is whenever the function was defined in postgres. A backwards compatible function is also added that provides the original.
* set the notification/listen channel to be the same as the table name for the queue, This probably won't affect much in the common case, but when multiple queues are involved from different processes, those processes shouldn't get spurious notifications for queues they are not interested in.
