Question

I\'m using Macbook

Psycopg2 works well when connecting the localhost db (PostgreSQL on Mac). The error was raised when I tried to connect PostgreSQL db on a Windows1

Answer 1

Adding ?gssencmode=disable to the connection string worked for me:

import pyodbc
from sqlalchemy import create_engine

engine = create_engine(f'postgresql://{user}:{password}@localhost:5432/database_name?gssencmode=disable')
