PostgreSQL error: Fatal: role "username" does not exist

🚧 PostgreSQL Error: Fatal: role "username" does not exist 🚧

Are you facing the PostgreSQL error "Fatal: role 'username' does not exist" while setting up or working with your PostgreSQL database? Don't worry, you're not alone. This error is quite common and can occur for various reasons. But fear not, we're here to help you understand the problem and find an easy solution.

Understanding the Error

The error message you're seeing is indicating that the specified role or username does not exist in your PostgreSQL database. A role in PostgreSQL is similar to a user account and is used to control access and permissions. If a role or username doesn't exist, you won't be able to perform any operations associated with that role.

Possible Causes

There can be several reasons why you're encountering this error. Let's discuss a few common scenarios:

1. Role Not Created

If you're trying to use a role that hasn't been created in your PostgreSQL database, you'll receive this error. This usually happens when you haven't explicitly created the role or if it was accidentally deleted.

2. Incorrect Role Name

You might be entering an incorrect role or username, leading to the error. Double-check the spelling and ensure that the role name is accurate.

3. Role Not Granted Sufficient Privileges

Even if a role exists, it may not have the necessary privileges to perform certain operations. For example, if you're trying to create a database with a role that doesn't have the necessary permissions, you'll encounter this error.

Easy Solutions

Now that you have a better understanding of the error and its potential causes, let's explore some easy solutions to resolve it:

1. Create the Role

If the role doesn't exist in your PostgreSQL database, you can create it using the CREATE ROLE command. Open your PostgreSQL command-line interface and enter the following command:

CREATE ROLE username;

Replace username with the desired name for your role. Once the role is created, you should be able to perform operations using that role without encountering the error.

2. Grant Sufficient Privileges

If the role exists but doesn't have the necessary privileges, you can grant them using the GRANT command. For example, if you want to grant the role the ability to create databases, you can use the following command:

GRANT CREATEDB TO username;

Replace username with the name of the role to which you want to grant privileges. This will allow the role to create databases without encountering the error.
