 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.
