Comment:
> So I had a django JSONField table with column called logs which is a
json field [ Not jsonb field ].
Django doesn't support pointing fields designed to work with certain
database data types to others, `JSONField` is not exception.
> Instead of doing this, why don't we check if the content/value parsed
from db is list or dict, by default python types for json
> If yes - Don't do anything
> If no and is a string instance - then perform json.loads() to it
If you need this feature simply subclass `JSONField` and override it's
`from_db_value` method. Note that if you use this approach you won't be
able to implement support for the `decoder` option as this requires the
decoding to be performed by the field itself and not from psycopg.
