+# n8n with PostgreSQL and pgvector Extension
+
+Starts n8n with PostgreSQL as database, including the PGvector extension for vector similarity searches.
+
+## Features
+
+- PostgreSQL database for n8n
+- PGvector extension for storing and querying vector embeddings
+
+## What's Possible?
+
+This Docker Compose setup delivers a ready-to-use PostgreSQL database with **PGvector** extension, enabling powerful vector-based AI capabilities right out of the box.
+
+### Example: RAG Workflow with pgvector
+
+The diagram below shows a sample n8n workflow that demonstrates Retrieval-Augmented Generation (RAG) capabilities using the PostgreSQL/pgvector backend:
+
+![AI-Powered Semantic Search Workflow](./rag_pg_vector_workflow_example.png)
+
+This example workflow illustrates:
+- Document embeddings storage using Google Gemini embeddings 001
+- Semantic similarity searches against your vector database
+- AI reasoning with Google Gemini Flash 2.0 as the LLM
+- A complete RAG pipeline implementation with minimal configuration
+
+## Start
+
+To start n8n with PostgreSQL and pgvector extension, simply run docker-compose by executing the following command in the current folder.
+
+**IMPORTANT:** But before you do that change the default users and passwords in the [`.env`](.env) file!
+
+```
+docker-compose up -d
+```
+
+To stop it execute:
+
+```
+docker-compose stop
+```
+
+## Configuration
+
+The default name of the database, user and password for PostgreSQL can be changed in the [`.env`](.env) file in the current directory.
+
+## PGVector Store Information
+
+This setup automatically creates:
+
+1. The pgvector extension in your PostgreSQL database
+2. An embeddings table with the following schema:
+
+```sql
+CREATE TABLE embeddings (
+  id SERIAL PRIMARY KEY,
+  embedding vector,
+  text text,
+  created_at timestamptz DEFAULT now()
+);
+```
+
+You can use this table to store vector embeddings from AI models for semantic search, similarity comparison, and other vector-based operations in your n8n workflows.
+
+## Accessing PostgreSQL with pgvector
+
+The PostgreSQL instance is exposed on port 15432 (to avoid conflicts with any local PostgreSQL installations). You can connect to it using:
+
+```
+psql -h localhost -p 15432 -U [POSTGRES_USER] -d [POSTGRES_DB]
+```
