安装部署要点(README 精选)

Installation

Getting Started

Enable the extension (do this once in each database where you want to use it)

CREATE EXTENSION vector;

Create a vector column with 3 dimensions

CREATE TABLE items (id bigserial PRIMARY KEY, embedding vector(3));

Insert vectors

INSERT INTO items (embedding) VALUES ('[1,2,3]'), ('[4,5,6]');

Get the nearest neighbors by L2 distance

SELECT * FROM items ORDER BY embedding <-> '[3,1,2]' LIMIT 5;

Also supports inner product (<#>), cosine distance (<=>), and L1 distance (<+>)

Note: <#> returns the negative inner product since Postgres only supports ASC order index scans on operators

Installation Notes – Linux and Mac

Installation Notes – Windows

常用命令(从 README 提取)

cd /tmp
git clone --branch v0.8.1 https://github.com/pgvector/pgvector.git
cd pgvector
make
make install # may need sudo

export PG_CONFIG=/Library/PostgreSQL/18/bin/pg_config

sudo --preserve-env=PG_CONFIG make install

通用部署说明(适用于大多数项目)

  1. 下载源码并阅读 README
  2. 安装依赖(pip/npm/yarn 等)
  3. 配置环境变量(API Key、模型路径、数据库等)
  4. 启动服务并测试访问
  5. 上线建议:Nginx 反代 + HTTPS + 进程守护(systemd / pm2)
