27437	Can't create GinIndex on ArrayField(CITextField)	Davide Setti	Mads Jensen	"I have a model like:

{{{#!python
class MyModel(models.Model):
    column = ArrayField(
        CITextField(max_length=255),
    )

    class Meta:
        indexes = [
            GinIndex(fields=['column'], name='mygin')
        ]
}}}

Migration fails because:

{{{
django.db.utils.ProgrammingError: data type citext[] has no default operator class for access method ""gin""
HINT:  You must specify an operator class for the index or define a default operator class for the data type.
}}}
