1. Trigger procedures need to return opaque.
2. 'now' should probably be now().
3. Can the SQL language handle this?
Here is how I did more or less the same:
DROP TRIGGER auto_modified_trig ON en_dirs;
DROP FUNCTION auto_modified();
CREATE FUNCTION auto_modified() RETURNS opaque AS '
BEGIN
NEW.modified = now();
RETURN NEW;
END;
' LANGUAGE 'plpgsql';
CREATE TRIGGER auto_modified_trig BEFORE INSERT OR UPDATE ON en_dirs
FOR EACH ROW EXECUTE PROCEDURE auto_modified();
-- It may not be the _right_ way to do it, but I think it works.
