There is this scenario:
test=# CREATE DOMAIN things AS INT CHECK (VALUE > 5);
CREATE DOMAIN
test=# CREATE TABLE abc (id SERIAL, stuff things);
NOTICE: CREATE TABLE will create implicit sequence "abc_id_seq" for
serial column "abc.id"
CREATE TABLE
test=# INSERT INTO abc (stuff) VALUES (55);
INSERT 0 1
test=# ALTER DOMAIN things ADD CONSTRAINT meow CHECK (VALUE < 11) NOT VALID;
ERROR: column "stuff" of table "abc" contains values that violate the
new constraint
STATEMENT: ALTER DOMAIN things ADD CONSTRAINT meow CHECK (VALUE < 11)
NOT VALID;
