  "description": "A PostgreSQL index access method for pgvector's vector type: a per-point int8 PCA sketch with an HNSW router over the sketches, a calibrated or exact lower bound that prunes before heap fetches, one shared in-memory image per index generation, and a log of inserts and tombstones compacted by VACUUM. L2 and cosine operator classes; filtered scans in batches.",
