I am not trying to pick on the issue but I do think it is important to
recognize that literally only those in the know, are going to ever touch
the postgresql.conf.

I deal with lots of customers, who employ lots of programmers that I
have often heard, "There is a postgresql.conf?". Why? Because they are
user space programmers using an ORM or other such tech that allows them
to never actually login to postgresql or a shell or anything once they
edit the pg_hba.conf.
