PostgreSQL

Persist Agno sessions and other data in PostgreSQL.

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

Usage

Start in a virtual environment.

Install Agno, SQLAlchemy, the binary Psycopg driver, and the OpenAI client:

uv pip install agno sqlalchemy "psycopg[binary]" openai
postgres_for_agent.py
from agno.agent import Agent
from agno.db.postgres import PostgresDb

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

db = PostgresDb(db_url=db_url)
agent = Agent(db=db)

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 \
