Bug reference: 1278
Logged by: Michael Howitz

PostgreSQL version: 7.3.7
Operating system: 2.6.8-gentoo-r3
Description: PL/pgSQL: ROWTYPE does not care for droped columns
Details:
IF you drop a column on a Table which is accessed via a PL/pgSQL-Function
using tablename%ROWTYPE you get an Error. It seems that ROWTYPE does not
take care about droped columns.
Example in code:
CREATE TABLE test (
id SERIAL,
start_date DATE,
testing INTEGER);
INSERT INTO test (start_date, testing) VALUES ('2003-05-03', 1);
SELECT * from test;
-- test.id will be 1
ALTER TABLE test DROP COLUMN start_date;
CREATE OR REPLACE FUNCTION dcTest(INTEGER) RETURNS INTEGER AS
'
DECLARE
tid ALIAS FOR $1;
test_rec test%ROWTYPE;
BEGIN
SELECT INTO test_rec *
FROM test
WHERE id = tid;
RETURN test_rec.testing;
END;
' LANGUAGE 'plpgsql';
SELECT dcTest(1);
gives the following Error:
WARNING: plpgsql: ERROR during compile of dctest near line 0
ERROR: cache lookup for type 0 of test.........pg.dropped.2........ failed
This code works correct in 7.4.1-dbExperts but also fails in
7.3.4-dbExperts.
