Open-source psql_bm25s speeds up PostgreSQL retrieval for multi-agent systems by 23x

开源psql_bm25s，让PostgreSQL多智能体检索提速23倍

The team open-sourced psql_bm25s, a native PostgreSQL access method for exact BM25 retrieval, and says it runs about 23x faster than pg_search on standard benchmarks.

Why it matters: HKR-H/K/R pass via the 23x retrieval-speed hook, named Postgres access method, and RAG latency pressure. Single-source release details lack independent reproduction and production constraints, so it stays in the lower featured band.
