Memory with PostgreSQL

Store user memories in PostgreSQL by passing PostgresDb as the agent's database.

Store and recall user memories with an agent backed by PostgreSQL.

Code

mem-postgres-memory.py
from agno.agent import Agent
from agno.db.postgres import PostgresDb

# Setup Postgres
db_url = "postgresql+psycopg://ai:ai@localhost:5532/ai"
db = PostgresDb(db_url=db_url)

agent = Agent(
    db=db,
    update_memory_on_run=True,
)

agent.print_response("My name is John Doe and I like to play basketball on the weekends.")
agent.print_response("What do I do on weekends?")
