--------------------------------------------+------------------------
With the following model:
```
from django.contrib.postgres.fields import JSONField
from django.db import models
class Subscription(models.Model):
inputs = JSONField()
```
I'd like this query to work (assuming a inputs look like `{'first_name':
'...'}`:
```
Subscription.objects.filter(inputs__first_name__unaccent__icontains="...")
```
But it fails with:
```
django.db.utils.ProgrammingError: operator does not exist: jsonb #> text
LINE 1: ...%' OR UPPER("subscriptions_subscription"."inputs" #> ARRAY['...
^
HINT: No operator matches the given name and argument type(s). You might
need to add explicit type casts.
```
cecef94275118dc49a1b0d89d3ca9734e2ec9776 registered a bunch of lookups for
chaining after a key transform, but unaccent wasn't included. I suggest to
include it as well.
