Chat with PostgreSQL Database

Ask questions about your database — get instant answers with AI.

This workflow lets users query a PostgreSQL database using plain language via n8n’s chat interface. An AI Agent interprets the question, explores the database schema if needed, runs the correct SQL query, and responds with a human-friendly answer.

Perfect for analysts, support teams, and non-technical users who need fast insights from your database — without writing SQL.

📂 Runs tools like Execute SQL, Get Table List, and Get Table Definition as needed
📝 Forms and executes the SQL query automatically
