postgres login asks for non superuser password

Question

I set up postgres according to the instructions for Windows 10 but every time I try to run psql it asks for a non superuser password which I haven't created. How do I make it ask for the superuser without using psql -U postgres command every time? Or how can I set/change a password for a non superuser? I've tried using ALTER ROLE to change the password but get role [username] does not exist as an error message.

By default, psql tries to use your OS username as a database username. Presumably this role hasn't been created in your database, hence the "does not exist" error.

You can override this default by setting the PGUSER environment variable .
