constraint deferred but fails?

Hello,

I have deferred the only fk constraint to this table inside a
transaction, but I still cannot delete rows from it.

How is that possible?


master=> ALTER TABLE doc.display_mode disable trigger user;
ALTER TABLE
master=> BEGIN;
BEGIN
master=> SET CONSTRAINTS doc.fk_book_display_mode_id DEFERRED;
SET CONSTRAINTS
master=> DELETE FROM doc.display_mode;
ERROR:  update or delete on table "display_mode" violates foreign key
constraint "fk_book_display_mode_id" on table "book"
DETAIL:  Key (id)=(1) is still referenced from table "book".
master=>
