面向前沿 GenAI 应用的 SQL 原生向量数据库
用普通 SQL 语法即可执行向量搜索、文本搜索、过滤搜索与复杂的 SQL-向量联表查询，索引通过一条 ALTER TABLE 语句创建。
专用索引引擎，官方称相比专用向量数据库可带来约三倍速度与三倍成本节省，并优化了数据写入与索引构建。
将向量相似度与 BM25 全文检索、元数据过滤相结合，提升检索增强生成流程的检索质量与上下文支撑。
全托管产品，集成多种流行语言、框架与 LLM 工具，并包含面向 AI 应用的可观测性能力。
为 AI 代理在你的 Postgres 上提供图、向量与文本检索
通过一个一致的接口同时查询图、向量、全文与混合检索，无需把多个系统拼在一起。
开源引擎 pgGraph 可跨记录沿关系遍历，无需搬迁数据即可实现多跳与最短路径式检索。
基于嵌入的语义搜索与稀疏、全文匹配相结合，兼顾语义与精确词条的查询需求。
仪表盘演练场、用于导入与配置的 CLI，以及强类型 Python SDK，让原型验证到正式上线一气呵成。
