Creating extension using migrationsLink to this heading#

You can create a PostgreSQL extension in your database using a migration file. This example creates an hstore extension, but the same principles apply for other extensions.

Set up the hstore extension in PostgreSQL before the first CreateModel or AddField operation that involves HStoreField by adding a migration with the HStoreExtension operation. For example:

from django.contrib.postgres.operations import HStoreExtension

class Migration(migrations.Migration):
    ...

    operations = [
        HStoreExtension(),
        ...
    ]

Creating the extension requires a database user with superuser privileges. If the Django database user doesn't have superuser privileges, you'll have to create the extension outside of Django migrations with a user that has the appropriate privileges. In that case, connect to your Django database and run the query CREATE EXTENSION IF NOT EXISTS hstore;.
