How To Connect Postgres For AI Agent Memory (n8n tutorial)
In this video, I show you how to solve one of the biggest problems with n8n AI Agents: memory loss. We'll replace the default "Simple Memory" with a scalable, persistent PostgreSQL database so your agent can remember conversations forever.
We'll cover:
Why "Simple Memory" isn't reliable for production AI agents (it erases on save).
How to set up a FREE PostgreSQL database in 5 minutes using Supabase.
How to connect your Supabase database to n8n as a credential.
How to use the "Postgres Chat Memory" node to give your AI agent long-term, persistent memory.
How chat history is stored in the database and how Session IDs work.
