FOREIGN KEY migration of syntax, help needed

Hi,

Quick question:

My old database has the old-style FOREIGN KEY syntax:

CREATE CONSTRAINT TRIGGER "<unnamed>"
AFTER INSERT OR UPDATE ON assettype
FROM assettype
NOT DEFERRABLE INITIALLY IMMEDIATE
FOR EACH ROW
EXECUTE PROCEDURE "RI_FKey_check_ins"('<unnamed>', 'assettype', 'assettype', 'UNSPECIFIED', 'pid', 'id');

CREATE CONSTRAINT TRIGGER "<unnamed>"
AFTER DELETE ON assettype
FROM assettype
NOT DEFERRABLE INITIALLY IMMEDIATE
FOR EACH ROW
EXECUTE PROCEDURE "RI_FKey_cascade_del"('<unnamed>', 'assettype', 'assettype', 'UNSPECIFIED', 'pid', 'id');

CREATE CONSTRAINT TRIGGER "<unnamed>"
AFTER UPDATE ON assettype
FROM assettype
NOT DEFERRABLE INITIALLY IMMEDIATE
FOR EACH ROW
EXECUTE PROCEDURE "RI_FKey_cascade_upd"('<unnamed>', 'assettype', 'assettype', 'UNSPECIFIED', 'pid', 'id');

I was wondering if I need to worry about the RI_FKey_check_ins statement.

Will the following take care of all three statements?

ALTER TABLE ONLY assettype
ADD CONSTRAINT at_fk_1 FOREIGN KEY (pid) REFERENCES assettype(id)
ON UPDATE CASCADE ON DELETE CASCADE;

Are there any other gottcha's when doing this type of migration?
(I need to use the FKEY syntax, so a schema visualizer will show the
foreign key relationships).

thanks a ton,

mike
