From the 7.2.1 documentation:
SELECT setval('foo', 42);           Next nextval() will return 43
SELECT setval('foo', 42, true);     Same as above
SELECT setval('foo', 42, false);    Next nextval() will return 42

So you want to use (assuming you really want the next value to be 1):
SELECT setval('your_sequence', 1, false);
