I have a Django app and a Postgresql database (in production). Now I want to intall pg_trgm extension for Postgres. But I can't find any step-by-step instructions for installing it from Django app. I have a superuser status. How to do it correctly?

  1. add 'django.contrib.postgres' in your INSTALLED_APPS

  2. add a customer migration file in the app's migration folder. (The migration files are indexed, It's better to follow that index. e.g. 0044_customer_migrations.py)

  3. add TrigramExtension in your migration file

    from django.contrib.postgres.operations import TrigramExtension

class Migration(migrations.Migration):
    dependencies = [
        ('myapp', '0043_latest_migrations'),
    ]

    operations = [
        TrigramExtension(),
    ]

  4. run migrate

    python manage.py migrate
