CommunityToolkit.VectorData.PgVector

This connector uses Postgres to implement Semantic Memory. It requires the pgvector extension to be installed on Postgres to implement vector similarity search.

What is pgvector?

pgvector is an open-source vector similarity search engine for Postgres. It supports exact and approximate nearest neighbor search, L2 distance, inner product, and cosine distance.

How to install the pgvector extension, please refer to its documentation.

This extension is also available for Azure Database for PostgreSQL - Flexible Server and Azure Cosmos DB for PostgreSQL.

Quick start

  1. To install pgvector using Docker:
docker run -d --name postgres-pgvector -p 5432:5432 -e POSTGRES_PASSWORD=mysecretpassword pgvector/pgvector
  1. Create a database and enable pgvector extension on this database
docker exec -it postgres-pgvector psql -U postgres

postgres=# CREATE DATABASE sk_demo;
postgres=# \c sk_demo
sk_demo=# CREATE EXTENSION vector;

Note, "Azure Cosmos DB for PostgreSQL" uses SELECT CREATE_EXTENSION('vector'); to enable the extension.

For more information, see the Microsoft.Extensions.VectorData documentation.
