Postgresql - 用户密码验证失败

Question

Well, I've been working on a project on Django, but a friend of mine was facing a problem so he sent me his project (The entire folder). Anyway, I tried to run the server but it didn't work. I tried to change the password and the username from the settings file, and when I tried to access the user, the username was changed (as the sql shell recognized it, I think ¯_(ツ)_/¯), but whenever I try to login with the password I wrote in the settings file it produces the following error:

django.db.utils.OperationalError: FATAL: password authentication failed for user "Youssef"

Here's the DATABASE part in the settings.py file:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'Boards_django',
        'USER': 'Youssef',
        'PASSWORD': '000000',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

BTW, the database is recognized by the PgAdmin4:

Any idea what should I do???

Side note: I can't access the user, hence I'm not able to use any of the commands of postgresql Also, when I try to run the server or make anything on the database from VS Code, It raises the following error:

django.db.utils.OperationalError: FATAL: password authentication failed for user "Youssef"

Here's the data in the pg_hba.conf

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     scram-sha-256
# IPv4 local connections:
host    all             all             127.0.0.1/32            scram-sha-256
# IPv6 local connections:
host    all             all             ::1/128                 scram-sha-256
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     scram-sha-256
host    replication     all             127.0.0.1/32            scram-sha-256
host    replication     all             ::1/128                 scram-sha-256

Answer 1

There are several possibilities:

• you used the wrong password

• there is no SCRAM-SHA-256 password set for the user

  This could be either because no password is set, or because the password_encryption parameter is set to md5 , or because the password has not been changed after password_encryption was changed.

  To see the current setting:

   SHOW password_encryption;

  To see the password:

   SELECT rolpassword FROM pg_authid WHERE rolname = 'Youssef';

Answer 2

well, the problem was that my friend had a slight spelling difference in his database, when I added it to my databases in the PgAdmin page, It worked perfectly.
