Why PostgreSQL Row-Level Security Is the Right Approach to Django Multitenancy

The article explores why PostgreSQL Row-Level Security (RLS) is a superior approach to Django multitenancy compared to alternatives like separate databases, schema-per-tenant, or application-level filtering. The author argues that application-level tenant filtering is fragile because developers inevitably forget to apply filters in background tasks, management commands, or raw SQL queries. By using RLS via the django-rls-tenants library, tenant isolation is enforced at the database level regardless of how queries are constructed.
