Polygres 總結
Polygres turns Postgres into working memory for AI agents. Retrieve structured rows, connected relationships, semantic matches, and full-text results through one hybrid API. All without a separate vector store, graph database, or sync pipeline. Build grounded agents over the data you already have, with relational, graph, and vector context joined at the source. Use the managed cloud or self-host with our open source components. Polygres is currently free to use, just sign up!

使用對比
如何使用Dagster？
To use Dagster, you can get started with a free 30-day trial or book a demo. The platform allows you to develop and test pipelines, monitor data quality, track complete data lineage, and leverage metadata and source observability. It supports testing code in any development stage locally, enabling automatic deployment to staging environments and confident shipping of data and AI products faster.
如何使用Polygres？
Create a Polygres managed instance or install the open-source components on an existing PostgreSQL database. Connect your schema and use the SDK or retrieval API to submit a natural-language query with options such as graph traversal depth, filters, and token limits. Polygres combines relational, graph, vector, and text results into one ranked, token-ready context block that can be passed directly to an AI agent.
