I want to fix this bug, however I can't see how the example below is failing... (Obeys dropped columns) I'm not up with my SRFs, so would someone be able to post a concise SQL script that demonstrates the failure?
I can see in the code that it should be failing, but I need a demonstrated example...
Here is a self contained example using cvs tip:
CREATE TABLE fk_test (f1 int, f2 int); insert into fk_test(f1, f2) values(1, 21); insert into fk_test(f1, f2) values(2, 22);
ALTER TABLE fk_test DROP COLUMN f2; ALTER TABLE fk_test ADD COLUMN f3 int;
insert into fk_test(f1, f3) values(3, 33); insert into fk_test(f1, f3) values(4, 34);
regression=# select * from fk_test ; f1 | f3 ----+---- 1 | 2 | 3 | 33 4 | 34 (4 rows)
CREATE OR REPLACE FUNCTION test()
RETURNS SETOF fk_test AS '
DECLARE
rec fk_test%ROWTYPE;
BEGIN
FOR rec IN SELECT * FROM fk_test LOOP
RETURN NEXT rec;
END LOOP;
RETURN;
END;
' LANGUAGE 'plpgsql';regression=# select * from test(); f1 | f3 ----+---- 1 | 2 | 3 | 4 | (4 rows)
