# Persistent Session with Database

This example demonstrates how to use persistent session storage with a PostgreSQL database to maintain team conversations across multiple runs.

## Code

```python cookbook/examples/teams/session/01_persistent_session.py theme={null}
from agno.agent.agent import Agent
from agno.db.postgres import PostgresDb
from agno.models.openai import OpenAIChat
from agno.team import Team

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"))

team = Team(
    model=OpenAIChat(id="gpt-5-mini"),
    members=[agent],
    db=db,
)

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