Could you build this?
Partial Basic tenant filters are straightforward, but building bulletproof multi-tenant connection pooling, PgBouncer session cleanup, and automatic PostgreSQL Row-Level Security policy generation requires deep database and framework internals.
What it would actually take: The stack comprises a Spring Boot starter integrating with HikariCP, Hibernate, PgBouncer, and PostgreSQL Row-Level Security (`SET LOCAL app.current_tenant`). The hardest challenge is preventing cross-tenant data leaks caused by pooled connection reuse across thread pools, reactive streams, and virtual threads, as well as handling schema migrations safely across tenant boundaries. Deep expertise in PostgreSQL internals, connection pooling semantics, and Spring lifecycle internals is required.
