We’re sunsetting pg_embedding in favor of pgvector

The Hierarchical Navigable Small World (HNSW) index has been introduced in Postgres, allowing for vector search to scale with the database. However, due to overlap and redundancy between HNSW and pgvector, pg_embedding will be sunsetting and its efforts will be redirected towards pgvector. This move aims to streamline the experience for Postgres users and contribute to a single project, pgvector, in the vector search space. The team is committed to improving vector search in Postgres and actively participating in discussions on pgvector, working on techniques to address challenges with larger datasets.
