Postgresql: Fatal: Password Authentication Failed For User "douglas"

I am trying to migrate a DB from sqlite to postgresql...so I typed: sudo -u postgres psql postgres=# ALTER USER postgres WITH PASSWORD 'newpassword'; and the output returns ALTER

Solution 1:

The SQL you are running does not match the user you are attempting to use.

You will need to create the user if it does not exist:

CREATEUSER douglas WITH PASSWORD 'vamointer';

or if it does exist, change that user's password instead.

ALTERUSER douglas WITH PASSWORD 'vamointer';

Once you have done that you should have more luck. You may need to assign permissions to that user as well.

Solution 2:

If you are bone-headed like me and have used 'USERNAME' instead of 'USER' in your Django database configs in settings.py, make sure you change it to 'USER' else you will see this same error. Hope this helps someone like me down the road.

Solution 3:

Special characters in postgresql are converted to different characters while execution. Make sure you do not have special characters (#,$,etc..) in your password.

If you do, change the postgresql password as follows:

sudo -u postgresql psql
postgresql=#ALTERUSER yourusername WITH PASSWORD 
'set_new_password_without_special_character';

Make sure you do not forget the ; at the end of postgresql command. Then run python manage.py and it should work!

Solution 4:

You can try this:

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.postgresql',
    'NAME': 'telusko',
    'USER': 'postgres', #in place we should always be write USER only if we write USENAME then it will give error.
    'PASSWORD': '1234',
    'HOST':'localhost',
}}

Solution 5:

It's also possible that your PostgreSQL server is not running. Please run next command, to check if postgres is running:

sudo service postgresql status

If not please run it, using:

sudo service postgresql start

Also, you can have wrong port in your settings. To check where Postgres is running use:

sudo netstat -plunt |grep postgres

And after update PORT in DATABASE config in Django settings
