Ok, fine also.
And not the Connection object on which it was received? Ok, maybe it's
not needed: When I want to do some db stuff within the callback, should
not make a difference on what connection I do that.
Few other design Qs:
Is it possible to UNLISTEN?
Or unregister a callback on a channel? Or set it to None?
Are callbacks for channels registered "globally" or per connection?
Can there be only one callback at most registered per channel?
