Hello. I use Django 4.2, psycopg2 2.9.6 and postgis/postgis:15-3.3-alpine
as database in my project.

Previously json field filtering worked as expected
'extra_data__hello="world"' returned me queryset where objects extra_data
json field contained {"hello": "world"}. Now I noticed queryset is empty.
After some manipulations with query it start work after adding "iexact".

I expected if json field is {"hello": "world"},
objects.filter(extra_data__hello="world") or
objects.filter(extra_data__hello=some_variable) should return this object
in query set, but it doesn't work.
objects.filter(extra_data__hello__iexact="world") fix this problem.

Here are queries example:
{{{
>>> token='world'
>>>
str(UserSocialAuth.objects.filter(extra_data__hello__exact=token).query)
'SELECT "social_auth_usersocialauth"."id",
"social_auth_usersocialauth"."user_id",
"social_auth_usersocialauth"."provider",
"social_auth_usersocialauth"."uid",
"social_auth_usersocialauth"."extra_data",
"social_auth_usersocialauth"."created",
"social_auth_usersocialauth"."modified" FROM "social_auth_usersocialauth"
WHERE ("social_auth_usersocialauth"."extra_data" -> hello) =
\'"\\"world\\""\''
>>>
str(UserSocialAuth.objects.filter(extra_data__hello__iexact=token).query)
'SELECT "social_auth_usersocialauth"."id",
"social_auth_usersocialauth"."user_id",
"social_auth_usersocialauth"."provider",
"social_auth_usersocialauth"."uid",
"social_auth_usersocialauth"."extra_data",
"social_auth_usersocialauth"."created",
"social_auth_usersocialauth"."modified" FROM "social_auth_usersocialauth"
WHERE UPPER(("social_auth_usersocialauth"."extra_data" ->> hello)::text) =
UPPER(world)'
}}}

Could you give me advice how to fix this issue?
Thank you
