No, it's still around:
regression=# select '-1 day'::interval;
interval
----------
-1 days
(1 row)
regression=# set datestyle = postgres;
SET
regression=# select '-1 day'::interval;
interval
-------------
@ 1 day ago
(1 row)
The most bletcherous aspect of Terry's original coding is that it fails
entirely, and silently, if the DateStyle setting isn't what it's
assuming...
