FHE-Postgres/pg_fhe

The project is a prototype-level implementation that wraps the Microsoft SEAL library for PostgreSQL. With only 18 stars and nearly zero activity (velocity 0.0) over its 3-year lifespan, it lacks any significant adoption or community momentum. While FHE is a highly complex domain, this specific project is a thin integration layer rather than a novel cryptographic breakthrough. The defensibility is very low because the value lies in the underlying SEAL library, not the PostgreSQL wrapper, which could be easily reproduced by a competent systems engineer. In the current market, companies like Zama are leading the open-source FHE charge with more modern schemes (TFHE), while major cloud providers (AWS, Azure) are more likely to implement confidential computing via TEEs (Trusted Execution Environments) or their own native FHE integrations into RDS/Aurora if performance improves. The project is likely an academic or personal experiment rather than a production-grade tool.
