I talked to Wez about this and he generally didn't know what listen/notify was
so he was pretty sure no one had gotten to the point of sending in a PDO
patch his way. He's certainly up for looking at a patch but had concern that
this might be something with too much of a postgresql specific tone, and
recommending investigating something like microsofts service broker
functionality to see if some common ground could be found. HTH.
