I have already done so. Under the paragraph about the queue filling up, I
have added:
"The function <function>pg_notify_queue_saturation</function> returns the
proportion of the queue that is currently occupied by pending
notifications."
A link from here back to the section in System Information Functions might
be sensible?
I will rename the function with _usage as you suggest, and add the
explanation of the return value in the docs.
Cheers,
BJ
