daf7d482db Refs #35234 -- Deprecated CheckConstraint.check in favor of .condition. 
Once the deprecation period ends CheckConstraint.check() can become the
documented method that performs system checks for BaseConstraint
subclasses.

3434dbd39d 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 5c23d9f0c3.

Thanks Alexandre Collet for the report.

54ea290e5b Fixed #30651 -- Made __eq__() methods return NotImplemented for not implemented comparisons. 
Changed __eq__ to return NotImplemented instead of False if compared to
an object of the same type, as is recommended by the Python data model
reference. Now these models can be compared to ANY (or other objects
with __eq__ overwritten) without returning False automatically.
