The __isnull lookup of JSONField must special case Value(None, JSONField()) left-hand-side in order to be coherent with its convoluted null handling. Since psycopg>=3 offers no way to pass a NULL::jsonb the issue is resolved by optimizing IsNull(Value(None), True | False) to True | False. Regression in5c23d9f0c3.
