That would mean it was a protocol change as well as an API change. If
the protocol was unchanged, the new API would generate the same
link-level events, only in a different way. And I seem to recall reading
somewhere that version 8.0 uses the same link-level protocol for
client-to-backend communication as 7.4 did. What you say contradicts it.
Maybe I'm wrong. My memory is not as good as it used to be... :-)
