[4.2.x] Fixed #34754 -- Fixed JSONField check constraints validation on
NULL values.
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 in 5c23d9f0c32f166c81ecb6f3f01d5077a6084318.
Thanks Alexandre Collet for the report.
