# Async Postgres for Team

> Store team sessions and run history asynchronously in PostgreSQL with AsyncPostgresDb.

`AsyncPostgresDb` stores a Team's sessions and run history asynchronously in [PostgreSQL](https://www.postgresql.org/). Use async Team methods such as `arun()` and `aprint_response()`.

## Usage

Install the `sqlalchemy`, `psycopg`, `openai`, and `ddgs` packages:

```shell theme={null}
uv pip install sqlalchemy psycopg openai ddgs
```

### Run PostgreSQL

Install [Docker Desktop](https://docs.docker.com/get-started/get-docker/), then start PostgreSQL with pgvector on port `5532`:

```bash theme={null}
docker run -d \
  -e POSTGRES_DB=ai \
  -e POSTGRES_USER=ai \
  -e POSTGRES_PASSWORD=ai \
  -e PGDATA=/var/lib/postgresql \
  -v pgvolume:/var/lib/postgresql \
  -p 5532:5432 \
  --name pgvector \
  agnohq/pgvector:18
```

```python async_postgres_for_team.py theme={null}
import asyncio
from typing import List

from agno.agent import Agent
from agno.db.postgres import AsyncPostgresDb
from agno.models.openai import OpenAIResponses
from agno.team import Team
from agno.tools.hackernews import HackerNewsTools
from agno.tools.websearch import WebSearchTools
from pydantic import BaseModel

db_url = "postgresql+psycopg_async://ai:ai@localhost:5532/ai"
db = AsyncPostgresDb(db_url=db_url)


class Article(BaseModel):
    title: str
    summary: str
    reference_links: List[str]


hn_researcher = Agent(
    name="HackerNews Researcher",
    model=OpenAIResponses(id="gpt-5.2"),
    role="Gets top stories from HackerNews.",
    tools=[HackerNewsTools()],
)

web_searcher = Agent(
    name="Web Searcher",
    model=OpenAIResponses(id="gpt-5.2"),
    role="Searches the web for information on a topic",
    tools=[WebSearchTools()],
    add_datetime_to_context=True,
)

hn_team = Team(
    name="HackerNews Team",
    model=OpenAIResponses(id="gpt-5.2"),
    members=[hn_researcher, web_searcher],
    db=db,
    instructions=[
        "First, search HackerNews for what the user is asking about.",
        "Then, ask the web searcher to search for each story to get more information.",
        "Finally, summarize each story and include its reference links.",
    ],
    output_schema=Article,
    markdown=True,
    show_members_responses=True,
)


async def main():
    try:
        await hn_team.aprint_response(
            "Write an article about the top 2 stories on HackerNews"
        )
    finally:
        await db.close()


if __name__ == "__main__":
    asyncio.run(main())
```
