We are sunsetting pg_embedding in favor of pgvector
Neon's pg_embedding extension was the first to introduce the Hierarchical Navigable Small World (HNSW) index to Postgres, but with the recent addition of HNSW to pgvector, we see little benefit to the Postgres community in continuing to develop a separate vector search extension.
After careful consideration, we believe it is in the best interest of our users and the broader Postgres community to sunset pg_embedding and continue our effort in the vector search space by contributing to pgvector.
As a result, we will no longer be committing to pg_embedding and will direct our efforts toward pgvector instead.
For anyone currently using pg_embedding, you will be able to continue using it on Neon. However, we strongly encourage you to migrate to pgvector. You can find the migration instructions in our documentation. See Migrate from pg_embedding to pgvector.
For more about our decision to sunset pg_embedding and what comes next for Neon in the vector search space, please refer to our blog post: We’re sunsetting pg_embedding in favor of pgvector.
Fixes & improvements
- Compute: With the announcement regarding sunsetting of
pg_embedding, Neon no longer permits new installations of thepg_embeddingextension. - Proxy: The timing of connection retries from the Neon proxy was adjusted to reduce connection wait times. The previous retry timing configuration could have resulted in making clients wait hundreds of milliseconds longer than necessary.
