Subject: [GENERAL] date stamp on update?

Is there a datatype in postgres that will automatically update the date when the row is updated?  I know I can do a timestamp and set the default to now() but once the row is inserted, and then edited, I want the column updated without editing my application code or adding a trigger.  Is this possible with Postgres?

Thanks!
