构建
您可以使用 pig build 命令构建 pgvectorscale 扩展的 RPM / DEB 包：
pig build pkg pgvectorscale # 构建 RPM / DEB 包
安装
您可以直接安装 pgvectorscale 扩展包的预置二进制包，首先确保 PGDG 和 PIGSTY 仓库已经添加并启用：
pig repo add pgsql -u # 添加仓库并更新缓存
使用 pig 或者是 apt/yum/dnf 安装扩展：
pig install pgvectorscale; # 当前活跃 PG 版本安装
pig ext install -y pgvectorscale -v 18 # PG 18
pig ext install -y pgvectorscale -v 17 # PG 17
pig ext install -y pgvectorscale -v 16 # PG 16
pig ext install -y pgvectorscale -v 15 # PG 15
pig ext install -y pgvectorscale -v 14 # PG 14
dnf install -y pgvectorscale_18 # PG 18
dnf install -y pgvectorscale_17 # PG 17
dnf install -y pgvectorscale_16 # PG 16
dnf install -y pgvectorscale_15 # PG 15
dnf install -y pgvectorscale_14 # PG 14
apt install -y postgresql-18-pgvectorscale # PG 18
apt install -y postgresql-17-pgvectorscale # PG 17
apt install -y postgresql-16-pgvectorscale # PG 16
apt install -y postgresql-15-pgvectorscale # PG 15
apt install -y postgresql-14-pgvectorscale # PG 14
创建扩展：
CREATE EXTENSION vectorscale CASCADE; -- 依赖: vector
用法
CREATE EXTENSION vectorscale CASCADE;
CREATE TABLE IF NOT EXISTS document_embedding (
id BIGINT PRIMARY KEY GENERATED BY DEFAULT AS IDENTITY,
metadata JSONB,
contents TEXT,
embedding VECTOR(1536)
);
-- 使用 diskann 索引方法创建向量索引
CREATE INDEX document_embedding_idx ON document_embedding
USING diskann (embedding);
-- 基于向量距离进行近似最近邻查询
SELECT *
FROM document_embedding
ORDER BY embedding <=> $1
LIMIT 10
