That wording is correct as it stands.
If I recall the previous discussion here, the problem is that the OP
is reading that and thinking that it applies also to errors generated
internally by libpq. We should, but don't, have any support for
assigning SQLSTATEs to those. But the server always emits a SQLSTATE
when sending a notice or error message --- read
send_message_to_frontend() if you doubt it.
