There might be something to the idea of demoting a few of the things
we've traditionally had as NOTICEs, though. IME, the following two
messages account for a huge percentage of the chatter:

NOTICE: CREATE TABLE will create implicit sequence "foo_a_seq" for
serial column "foo.a"
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index
"foo_pkey" for table "foo"

I'm not going to claim that nobody in the history of the world has
ever benefited from those notices ... but I would be willing to bet
that a large majority of the people, in a large majority of the cases,
do not care. And getting rid of them would surely make warnings and
notices that might actually be of interest to the user a lot more
visible.
