Postgres with Builtin File Systems

db9 is a serverless PostgreSQL platform designed for AI agents, combining a full SQL database with a cloud filesystem in a unified interface. It offers built-in auto-embeddings, vector search, environment branching, file storage, cron scheduling, and type generation — all manageable from the terminal with zero configuration. The tool targets use cases like personal assistants, research agents, and multi-agent automation by letting structured data live in Postgres while raw files coexist in the same workspace.
