Postgres：FK约束的问题

Question

如何解决FK约束？有触发器还是别的什么？

#IF "DELETE FROM human where name='a';", error due to the FK contraist.

# If the error, I want in the order:
# FIRSTLY. DELETE FROM address where name='a';
# SECONDLY. DELETE FROM human where name='a';


DROP TABLE human;
DROP TABLE address;

CREATE TABLE human(
        name varchar(300) PRIMARY KEY not null

);

CREATE TABLE address(
        name varchar(300)
                references human.name

);

Answer 1

CREATE TABLE address (
    name varchar(300) REFERENCES human (name) ON DELETE CASCADE
);

这就是你想要的吗？

Answer 2

Chapter 5.3.5. Foreign Keys精细手册非常有帮助。
