django - 按天过滤日期字段给出错误“用户定义的函数引发异常”

Question

当我按天或月或两者过滤 DateField 时：

today = date.today()
birthday = Paziente.objects.filter(natoil__month=today.month, natoil__day=today.day)

楷模

class Paziente(models.Model):
    natoil = models.DateField(blank=True, null=True)

给出错误：

OperationalError at /
user-defined function raised exception

请帮助 Django 1.11.4
