Persistent Session Storage

This example demonstrates how to create an agent with persistent session storage using PostgreSQL, enabling conversation history to be maintained across different runs.

Code

01_persistent_session.py

from agno.agent.agent import Agent
from agno.db.postgres import PostgresDb
from agno.models.openai import OpenAIChat

db_url = "postgresql+psycopg://ai:ai@localhost:5532/ai"

db = PostgresDb(db_url=db_url, session_table="sessions")

agent = Agent(
    model=OpenAIChat(id="gpt-5-mini"),
    db=db,
    session_id="session_storage",
    add_history_to_context=True,
)

agent.print_response("Tell me a new interesting fact about space")

Usage

1. Create a virtual environment

   Open the Terminal and create a python virtual environment.

   Mac

   python3 -m venv .venv
   source .venv/bin/activate
   

2. Install libraries

   pip install -U agno openai psycopg2-binary
   

3. Setup PostgreSQL

   # Make sure PostgreSQL is running
   # Update connection string in the code as needed
   

4. Export your OpenAI API key

   Mac/Linux

     export OPENAI_API_KEY="your_openai_api_key_here"
   

5. Create a Python file

   Create a Python file and add the above code.

   touch 01_persistent_session.py
   

6. Run Agent

   Mac

   python 01_persistent_session.py
