Lakebase Search
Postgres extensions that add an approximate nearest-neighbour index (lakebase_ann) and BM25 keyword ranking (lakebase_bm25) inside Lakebase.
Why it is worth watching
Vector and keyword search in the same query as the rows they belong to, without a second system. Enabling it on a project cannot be undone.
What Beta promises
Open to most customers but not for production: support runs through engineering, and the shape of it can still move. On by default on Premium, off on Enterprise.
| Who can use it | Most customers |
|---|---|
| Production use | No |
| Support | Engineering only |
| On by default | Premium yes, Enterprise no |

Where to read more
It is part of something we wrote up: The Data API and Postgres extensions — A PostgREST-compatible HTTP interface generated from the schema, and the Postgres extensions Lakebase ships — pgvector, PostGIS, pg_stat_statements and the rest — including the beta search indexes.
