Could you build this?
No Implementing a custom C-based PostgreSQL storage engine extension that alters table heap storage layout and integrates low-level vector indexing requires deep PostgreSQL internals and C systems programming knowledge.
What it would actually take: Requires deep C systems programming and mastery of PostgreSQL internal table access method (TAM) APIs, buffer management, WAL logging, and index-scan mechanics. The builder must write memory-safe C extensions that interface with SIMD-accelerated vector search libraries (like FAISS or USearch) while ensuring crash recovery and ACID compliance.
Discussion
1 comment analyzed.
Competitors mentioned: pgvector with HNSW index, pgvector IVFFlat index
Concerns raised: 22ms latency vs 14ms for HNSW (slower vector search), Limited to PostgreSQL 17+18 (version compatibility), IVF-PQ quantization bottleneck vs storage precision gains
