A example of this that I wrote is here:
https://github.com/shawn-hurley/rhscl-postgresql-apb

I tried to show two different workflows with this.

Another important note, is because of the lack of async bind, if the APB 
does not launch and return fast enough then an error will occur and the 
catalog can not resolve it at the moment.
