当表名更改后,如何更改PostgreSQL中对表的引用？

说我有:

CREATE TABLE example1 (
   id serial NOT NULL PRIMARY KEY,
   name varchar(100)
);

CREATE TABLE example2 (
   id serial NOT NULL PRIMARY KEY,
   example1fk integer REFERENCES example1 (id) DEFERRABLE INITIALLY DEFERRED
);

后来我做了:

ALTER TABLE example1 RENAME TO example3; 

如何更改外键约束的定义？

example1fk integer REFERENCES example1 (id) DEFERRABLE INITIALLY DEFERRED,
