Database error on insert (Compatability with postgresql)

I have set expiry length at +1week and warning period the same. Here is the error displaying on home page :

* warning: pg_query() [function.pg-query]: Query failed: ERROR: syntax error at or near ")" LINE 1: INSERT INTO password_expire () VALUES (18, 1270180800, 0) ^ in /usr/local/www/grcs-crchum.ca/www/includes/database.pgsql.inc on line 139.
