Async PostgreSQL

AsyncPostgresDb stores Agent, Team, and Workflow sessions, memories, knowledge, evaluations, and traces asynchronously in PostgreSQL.

Usage

Install the sqlalchemy, psycopg, and openai packages:

uv pip install sqlalchemy psycopg openai

async_postgres_for_agent.py

from agno.agent import Agent
from agno.db.postgres import AsyncPostgresDb

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

db = AsyncPostgresDb(db_url=db_url)
agent = Agent(db=db)

Use async methods such as Agent.arun() and Agent.aprint_response() with this database.

Run PostgreSQL

Install Docker Desktop, then start PostgreSQL with pgvector on port 5532:

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
