# 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

```python 01_persistent_session.py theme={null}
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")
```
