Improved vector search performance and relevance with pgvector 0.8.0 on Amazon Aurora PostgreSQL | Amazon Web Services

AWS said Amazon Aurora PostgreSQL now supports pgvector 0.8.0.

The update adds iterative_scan, better query planning, and improved recall for filtered ANN searches.

HNSW-based vector search reported up to 9x faster queries with much higher relevance.

It should help AI workloads like semantic search and RAG scale faster and more accurately on PostgreSQL.
