from agno.db.postgres import PostgresDb
from agno.memory import MemoryManager, UserMemory
from agno.models.openai import OpenAIResponses
from rich.pretty import pprint

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

memory_db = PostgresDb(db_url=db_url)

memory = MemoryManager(model=OpenAIResponses(id="gpt-5.2"), db=memory_db)

john_doe_id = "john_doe@example.com"
memory.add_user_memory(
    memory=UserMemory(memory="The user enjoys hiking in the mountains on weekends"),
    user_id=john_doe_id,
)
memory.add_user_memory(
    memory=UserMemory(
        memory="The user enjoys reading science fiction novels before bed"
