Depends on CORE1311

Test case:

-----------------
isql
create database 't.fdb';

create domain d1 integer default 3;

create table pk (a integer primary key);
create table fk (b d1 references pk on delete set default);

alter domain d1 set default 2;

-- Optional reconnection
exit;
isql t.fdb
--

insert into pk values (1);
insert into pk values (2);
insert into pk values (3);

insert into fk values (1);
insert into fk values (2);

delete from pk where a = 1;

-- Displays: "3; 2" instead of "2; 2"
select * from fk;
-----------------

The problem is that there is no BLR verb to modify a field to its default value, so the cascade trigger is created with the current default value of the field.
