#27338 closed Cleanup/optimization

Running an AlterField to change a CharField primary key to AutoField crashes — at Initial Version

Description

For example: change id = models.CharField(max_length=20, primary_key=True) to id = models.AutoField(primary_key=True). It generates this operation:

migrations.AlterField(
    model_name='foo',
    name='id',
    field=models.AutoField(primary_key=True, serialize=False),
),

Running it on PostgreSQ gives: django.db.utils.ProgrammingError: operator class "varchar_pattern_ops" does not accept data type integer. I'm not sure if this can be made to work sensibly. Is it possible to autopopulate the AutoField? I ran into this situation while investigating #27267.
