#25133: Changing a PositiveIntegerField to an IntegerField does not remove >=0
check in migration
----------------------------+----------------------------------
Reporter: jproffitt | Owner: nobody
Type: Bug | Status: new

Severity: Normal | Keywords: migrations, postgres
Triage Stage: Unreviewed | Has patch: 0

----------------------------+----------------------------------
When you change a `PositiveIntegerField` to just an `IntegerField`, the
>=0 database check in postgres is not removed when running the migration.
Initial migration:
{{{
('year', models.PositiveIntegerField(blank=True, null=True,)),
}}}
Alter migration:
{{{
migrations.AlterField(
model_name='art',
name='year',
field=models.IntegerField(blank=True, null=True),
preserve_default=True,
),
}}}
I'm left with having to do a `RunSQL` operation to remove the constraint.
