Forget my first reply, there is no date(text) function either...

But you can do that :

test=> select test, (test+19000000)::text::datetime::date from testint;
  test|      date
------+----------
980101|01-01-1998
971121|21-11-1997
720306|06-03-1972
(3 rows)

The test field is a int4 field, so you can do that (not very nice, but it
works) :)

Hope this helps !
