Error trying delete Window definition when the window is on ad_recentitem table

Hi guys,

I'm trying to delete a Window on dictionary definition but the window is related to table ad_recentitem. I change database definition for constraint with this code:

ALTER TABLE ad_recentitem
DROP CONSTRAINT adwindow_adrecentitem

ALTER TABLE ad_recentitem
ADD CONSTRAINT adwindow_adrecentitem FOREIGN KEY (ad_window_id)
REFERENCES ad_window (ad_window_id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE CASCADE DEFERRABLE INITIALLY DEFERRED

Can you add this code to migration script?
