We're excited to release pgvectorscale. Our team built this extension to make PostgreSQL a better database for AI and to challenge the notion that PostgreSQL and pgvector are not performant for vector workloads.

pgvectorscale is open-source under the PostgreSQL license and free to use on any PostgreSQL database.

Here are two helpful companion reads to the post linked by OP: A benchmark of how PostgreSQL with pgvector and pgvectorscale performs against Pinecone [1], and a technical deep dive into pgvectorscale's StreamingDiskANN index and Statistical Binary Quantization implementations [2].

Questions and feedback welcome!
