OK, seems 'Postgres' is a unique output format for 'date' too, even though
it doesn't look like the 'Postgres' timestamp output:

default
SET datestyle = 'ISO, MDY'; SELECT current_timestamp, current_date;
SET
now | date
-------------------------------+------------
2013-08-06 16:18:48.218555-04 | 2013-08-06

SET datestyle = 'SQL, MDY'; SELECT current_timestamp, current_date;
SET
now | date
--------------------------------+------------
08/06/2013 16:18:43.054488 EDT | 08/06/2013

SET datestyle = 'German, MDY'; SELECT current_timestamp, current_date;
SET
now | date
--------------------------------+------------
06.08.2013 16:18:59.026553 EDT | 06.08.2013

MDY
SET datestyle = 'Postgres, MDY'; SELECT current_timestamp, current_date;
SET
now | date
-------------------------------------+------------

DMY
SET datestyle = 'Postgres, DMY'; SELECT current_timestamp, current_date;
SET
now | date
-------------------------------------+------------

I don't think there is even a documentation change I can suggest.
