How to start Django models auto increment key from a certain number like 2456?

Question

In mysql if you want to start your auto-increment key from 2456 you can write AUTO_INCREMENT=2456

Also in PostgreSQL we can do this by using Sequence

CREATE SEQUENCE serial START 2456;
INSERT INTO distributors VALUES (nextval('serial'), 'nothing');

But in Django Rest Framework or Django by default auto-increment starts from 1. If I have a model like this

class Content(models.Model):
     title = models.CharField(max_length=70, blank=False, default='')
     description = models.CharField(max_length=200,blank=False, default='')
     published = models.BooleanField(default=False)

How can I make sure that the first Content starts from 2456?

Create a RunSQL--(Django Doc) operation

from django.db import migrations


class Migration(migrations.Migration):
    dependencies = [
        ('sample', '0003_content'),
    ]

    operations = [
        migrations.RunSQL(
            "ALTER SEQUENCE sample_content_id_seq RESTART WITH 1453"
        ),
    ]
