Well, I guess we disagree on this.
Why trashing the system with NOTIFYs no one listens to?
Of course, like Tom Lane suggested, I could create a table similar to now obsolete pg_listener and manage it from the
clientthat LISTENs and gets notifications.
Also, what sense pg_listening_channels() function makes, if it returns channels that I created (in my current
session/connection)?
I don't need this function to know whether I issued LISTEN my_channel or not.
