Multi-Tenant SaaS Database Architecture: PostgreSQL Row-Level Security (RLS), Indexing & Pooling

A production multi-tenant PostgreSQL architecture enforces hard tenant isolation by combining application-level query scoping with database-enforced Row-Level Security (RLS) policies bound to transaction-scoped session variables (`SET LOCAL app.current_tenant_id`), backed by leading-column `tenant_id` composite B-Tree indexes and PgBouncer transaction pooling.
