-- CORE-1518 Adding a non-null restricted column to a populated table renders the table inconsistent

-- CORE-4725 (Inconsistencies with ALTER DOMAIN and ALTER TABLE with DROP NOT NULL and PRIMARY KEYs)
-- CORE-4733 (Command "Alter table <T> alter TYPE <C> <DOMAIN_WITH_NOT_NULL" does not verifies data in column <C> and makes incorrect assignments in <C> to ZERO / JULIAN_DATE / ASCII(0) for types INT, TIMESTAMP and VARCHAR)

-- Source sample in the ticket:
-- create table dyd(c1 integer), insert one record with value = 1.
-- alter table dyd add c2 integer not null ==> did not raise exception but should.
-- All these statements should produce exception in 3.0:
alter table test alter c1 set not null;
alter table test alter c1 type dm_nn;
alter table test add c2 int not null; -- this also check for core-2696 ("alter table" command can add a field which has "not null" definition)
alter table test add c3 dm_nn;
-- still passed on 3.0 (does not verifies old data on new check condition):
-- alter table test add constraint test_nn check(c1 is not null); -- :(((
