Determine all listeners subscribed to notifcations and what channels

[Cory Tucker <cory.tucker@xxxxxxxxx>]

I'm interested in trying to figure out which channels have been subscribed to (using LISTEN).  From what I could tell via a little Googling, there used to be a table named pg_catalog.pg_listener that contained all this information, but that seems to have disappeared somewhere in the 9.x release (I'm using 9.3.x).

Is there a way to find out which channels have listeners?

thanks
