AI assistant for PostgreSQL: ask in plain language

# AI assistant for PostgreSQL: ask questions in chat and get data without SQL

This workflow enables conversational access to a Supabase/PostgreSQL database using an AI agent powered by LangChain and OpenAI. Users send natural language queries via chat — the assistant identifies the correct table, generates a precise SQL query, executes it, and returns structured results. It eliminates the need to write SQL manually, making database insights accessible to non-technical users.

## Who it´s for
- Analysts who need fast database access without writing SQL
- Developers automating chat-based database interactions
- Managers requesting data reports through simple text input

## What the automation does
- Processes incoming chat messages as natural language database queries
- Uses OpenAI to convert text into accurate SQL statements
- Retrieves table schemas and column definitions for context-aware query generation
- Executes safe SELECT queries against PostgreSQL/Supabase and returns results
- Supports JSON field analysis and dynamic condition building

## What´s included
- Ready-to-use n8n workflow with LangChain agent logic
- Trigger and handler logic for chat message inputs
- Integrations with Supabase, OpenAI API, and PostgreSQL
- Basic textual guide for deployment and adaptation

## Requirements for setup
- n8n instance (self-hosted or cloud)
- PostgreSQL database or Supabase project with read access
- OpenAI API key
- Configured database connection in n8n

## Benefits and outcomes
- Faster data retrieval by eliminating manual SQL writing
- Lowered data access barrier for non-technical team members
- Centralized querying via a unified chat interface
- Scalable foundation for internal BI tools
