## Problem description

When windos computers connected to redshift, the password error was reported, I was sure that my password was correct, and I was able to connect normally under mac, I suspected that it was special characters, but I changed the password to no special characters, only alphanumeric, and the error was still reported under windows, and the error content was:

{'S': 'FATAL', 'C': '28000', 'M': 'password authentication failed for user "ag_readonly"', 'F': '/home/ec2-user/padb/src/pg/src/backend/libpq/auth.c', 'L': '425', 'R': 'auth_failed'}
