pytest_sessionfinish cannot access database for cleanup

For a given scenario, I need to undo some migrations in order to let the test database be gracefully deleted. One of those migrations creates a replication subscription that avoids the database to be removed. The solution would be to use pytest_sessionfinish hook to undo some migrations and let the teardown process to run gracefully.

However, pytest_django is avoiding the hook to complete, denying database access to it. I cannot find a way around this in order to implement this. The result: the test database need to be removed manually, which breaks the entire deployment automation.

Is there any way of doing it?

Start at the pytest_sessionfinish hook and inspect how pytest-django handles database access during session teardown. Reproduce the migration and replication-subscription cleanup scenario described in the issue, then verify that the test database can be removed without manual intervention; no specific file or test is named.
