I know diddly-squat about pg_background, but judging from the symptoms
you mention, it's not very smart about functions declared to return
RECORD, which is what's happening under the hood if you use multiple OUT
parameters. You might have better luck if you create a named composite
type and declare the function to return that (which'll require some
internal notational changes in the function, but nothing too awful).
Or perhaps not. In any case, it'd be an idea to take this up with the
extension's author; maybe it can be improved in future releases.
