Pgvector
A Postgres extension that adds vector data types and similarity search.
pgvector turns Postgres into a vector database. For most production AI applications below the tens-of-millions-of-vectors scale, pgvector + a regular Postgres is the right choice — you keep ACID guarantees, your existing tooling, and one fewer system to operate. Above ~50M vectors or when sub-100ms latency is critical, dedicated vector DBs (Qdrant, Pinecone, Weaviate, Turbopuffer) start to pay off.
