Supabase pgvector

Supabase pgvector is the open-source PostgreSQL extension for storing, indexing, and querying vector embeddings at scale.

Supabase pgvector transforms your PostgreSQL database into a high-performance vector store, eliminating the need for a separate vector service. It leverages the robust `vector` extension to enable fast, accurate similarity searches (e.g., cosine distance) on high-dimensional embeddings (up to 1536 dimensions for models like OpenAI's `text-embedding-ada-002`). This unified architecture simplifies your stack: you can run complex SQL joins between transactional data and vector data, all within a single, proven, and scalable Postgres instance.
