After your patch Postgres still crashes on this test:
CREATE TYPE foo AS (a INT, b INT);
BEGIN;
DECLARE c CURSOR FOR SELECT (i, power(2, 30))::foo FROM generate_series(1,10) i;
FETCH c;
ALTER TYPE foo ALTER ATTRIBUTE b TYPE TEXT;
FETCH c;
COMMIT;
This test case was proposed in this thread, but I suggest treating this as a separate bug needing separate fix.
In my opinion in both cases (PL/pgSQL + CURSOR) we should error out instead of trying to remediate type changes.
