This code path is currently not covered by tests. It can be exercised with the following SQL pattern
CREATE TABLE temp_tbl (a text, b text); ALTER TABLE temp_tbl SET (toast_tuple_target = 128); ALTER TABLE temp_tbl ALTER COLUMN a SET STORAGE EXTERNAL; ALTER TABLE temp_tbl ALTER COLUMN b SET STORAGE EXTERNAL; INSERT INTO temp_tbl values(repeat('a', 4000), repeat('a', 120));
