This text discusses multi-tenancy architectures in Postgres databases, focusing on the database-per-user design. It highlights three main approaches to handling multiple users' data: shared schema, schema-per-user, and database-per-user. The advantages of a database-per-user strategy are outlined, including improved security, isolation, and control over geographic restrictions. The text also explores the concept of isolated vs. shared application environments and the importance of a control plane for managing multiple databases effectively. It concludes by emphasizing that while both approaches have their merits, the choice ultimately depends on specific business requirements and customer preferences.
