Comment:
I couldn't replicate - could you share a script?
I am using postgres 15 and Django 5.1.2
{{{
>>> MyModel.objects.create(name="Test", measure=measure_1)
<MyModel: MyModel object (1)>
>>> MyModel.objects.create(name="Test")
<MyModel: MyModel object (2)>
>>> MyModel.objects.create(name="Test", measure=measure_2)
<MyModel: MyModel object (3)>
>>> MyModel.objects.all().delete()
(3, {'app1.MyModel': 3})
>>> my_model = MyModel(name="Test")
>>> my_model.full_clean()
>>> my_model.save()
>>> my_model = MyModel(name="Test", measure=measure_1)
>>> my_model.full_clean()
>>> my_model.save()
>>> my_model = MyModel(name="Test", measure=measure_2)
>>> my_model.full_clean()
>>> my_model.save()
}}}
