Meh --- I do not think "emitted" is much of an improvement over "sent".
(I agree it's not great that these two places don't use matching
terminology, though.) Neither is clear as to where the message is
sent or emitted.
As for the other end of it, I don't like "delivered" because it presumes
that the processing action necessarily is to send the message to the
connected client. When a backend takes a message off the queue, it may
just drop it on the floor because its client is not listening to that
channel. Nonetheless, until it's done so that message must consume
queue space.
Maybe we could use terminology along the lines of "added to the
queue" and "removed from the queue"?
