The existing behavior dates from here:
http://archives.postgresql.org/pgsql-committers/2010-03/msg00245.php

As best I can tell there was no preceding discussion, just Simon
unilaterally deciding that this logging was required for debugging
purposes. (There is a followup thread in -hackers arguing about the
message wording, but nobody questioned whether it should come out
unconditionally.)

I'm of the opinion that the correct way of "lowering in later releases"
is to make the messages obey Log_connections. The "needed for debug"
argument seems mighty weak to me even for the time, and surely falls
down now.
