cascade delete

Hi,

I have following 2 tables in postgres DB. I created a cascade delete
constraint on image_id column of accomm_images which is a foreign key from
image tbale.

When I execute -> delete from accomm_images
It should delete all the child records of image table as well. But its not
happening.

CREATE TABLE image(
id int4 NOT NULL,
url int4 NOT NULL
);

CREATE TABLE accomm_images(
accomm_id int4 NOT NULL references accomm(id),
image_id int4 NOT NULL references image(id) on delete
cascade
);

Is there anything missing?

Thanks
Bhushan
