Обсуждение: Foreign Keys and ALTER RENAME TABLE

It doesn't appear that Foreign keys are updated when renaming the
table.  Causing references to become non-existant.


create table foobar ( id SERIAL);

INSERT INTO foobar DEFAULT VALUES;

INSERT INTO foobar DEFAULT VALUES;

INSERT INTO foobar DEFAULT VALUES;

create table barfoo (id int4 REFERENCES foobar (id) ON UPDATE CASCADE
ON DELETE CASCADE);



update foobar set id = 10 where id = 1;

-- Works as expected

alter table barfoo rename to farboo;

-- No warnings from above line!



update foobar set id = 12 where id = 2;

-- ERROR: Relation 'barfoo' does not exist
