The case that we're trying to cater to with the existing wording is
novice DBAs, who are likely to stare at such a message and not even
realize that pg_hba.conf is what they need to change. Frankly, by
the time anyone is using REJECT entries they are probably advanced
enough to not need much help from the error message; but what you
propose is an absolute lock to increase the number of newbie questions
on the lists by a large factor.
