psql: FATAL: database "<user>" does not exist

📝 Title: Troubleshooting "psql: FATAL: database '<user>' does not exist" Error on Mac

🖥️ Introduction: Are you experiencing trouble installing PostgreSql app on your Macbook? Don't worry, you're not alone. Many users have encountered the "psql: FATAL: database '<user>' does not exist" error, which prevents them from accessing the database console. In this guide, we'll address common issues and provide easy solutions to help you get your PostgreSql app up and running smoothly.

🔍 Understanding the Error: The error message "psql: FATAL: database '<user>' does not exist" occurs when the database that the application is trying to find does not exist. This error can arise during installation or when running the PostgreSql app console.

🛠️ Solutions to Fix the Error:

1. Solution 1 - Specify the Database: Use the -d flag followed by the database name to specify the database that psql should connect to. For example:

   psql -d template1

   This command ensures that psql connects to the template1 database, which is a default database automatically created by Postgres.app.

2. Solution 2 - Check the Application's Documentation: Refer to the application's documentation page for any specific instructions or troubleshooting steps. In this case, the documentation states that Postgres.app creates the $USER database on startup, which is the default database for psql when none is specified. Ensure that the $USER database is being created correctly.

3. Solution 3 - Reinstall the PostgreSql App: If the above solutions do not work, try uninstalling and reinstalling the PostgreSql app. Make sure to follow the installation instructions carefully to ensure a proper installation.

💡 Explanation: The reason behind using psql -d template1 or specifying a database is that Postgres.app creates the $USER database on startup, and by default, psql connects to the database with the same name as the current user. However, in some cases, this default behavior may not work, resulting in the "database '<user>' does not exist" error. By specifying a different database (template1 in this case), psql can successfully connect and open the console.
