    33The existence of extensions, which is tracked by database migration operations, is not different from other Postgres feature that the schema might require to create indices and fields such as collations and custom types.

    5 The ''problem'' here is that `migrate --run-syncdb`, which is relied upon by [https://github.com/django/django/blob/40bfd7b09aa0907b143e96f0b055538f476e544e/django/db/backends/base/creation.py#L68-L84 test database creation], has absolutely no knowledge of database migration operations that don't relate directly to models. All it does is [https://github.com/django/django/blob/40bfd7b09aa0907b143e96f0b055538f476e544e/django/core/management/commands/migrate.py#L434-L489 create models] by design.

    77To confirm the issue is not specific to `TEST_MIGRATE=False` yourself, try settings `MIGRATION_MODULES` entries to `None` for each of your `INSTALLED_APPS` and running `migrate --run-syncdb` against a fresh database, you should see the exact same failure.
