1. Create a model with `data = JSONField(db_index=True)`; makemigrations;
migrate
1. Add a `GinIndex(fields=['data'], name='foo')` to `_meta.indexes`;
makemigrations; migrate
1. Remove `db_index=True` from the `JSONField`; makemigrations; migrate
After step 2 there will be a Gin index on the `data` column on the model.
After step 3 there's _no_ index on the `data` column anymore.
