AI workloads are reshaping Postgres, and the battlefield centers on SerenDB, a Neon PostgreSQL fork tuned for AI agent workloads. It supports time-travel queries so you can see data as it existed at a moment in the past, and it packs scale-to-zero vector embeddings so idle databases cost almost nothing. A bold goal is 100ms branch creation to clone prod data for rapid agent testing. The project also pursues prompt-injection detection to harden AI-first databases [1].
Meanwhile, a wave of posts highlights how production workflows can run on Postgres for AI agents: TigerData's piece on 'Postgres for Agents' points to practical patterns [2].
On the tooling side, MCP server from Timescale (now Tiger Data) auto-injects Postgres best practices into AI context. The getprompttemplate tool lets the LLM auto-discover guidance without commands, designing a schema and injecting hypertable patterns [3]. It ships with versioned Postgres docs (15-17) and hybrid search, plus compatibility with Claude Desktop [3].
Meanwhile, Genesis DB's MCP Server previews AI access to event-sourced data, translating natural-language questions into Genesis DB queries and streaming results back. It makes event stores conversational, letting you ask 'What events exist in the system?' or 'How many users signed up last week?' without writing projections [4].
Together, these threads show PostgreSQL being repurposed as an AI-first data platform.
