Hm. This looks weird. What happened to the the change to toasted_col2 that was
in the "removed" line?
This corresponds to the following statement I think:
-- test update of a toasted key without changing it
UPDATE toasted_key SET toasted_col2 = toasted_col1;
which previously was inserted as:
INSERT INTO toasted_key(toasted_key, toasted_col1) VALUES(repeat('1234567890', 200), repeat('9876543210', 200));
so toasted_col2 should have changed from NULL to repeat('9876543210', 200)
Am I misreading something?
