Documentation Improvement: Clarify PostgreSQL Database Configuration Steps

[tugascrown204]

Issue

The current documentation provides a general overview of setting up a PostgreSQL database but lacks detailed instructions on specific configuration settings and potential pitfalls.

Suggested Improvement

1. Add Examples: Include examples of the configuration file for PostgreSQL settings. For instance, demonstrate what the database name, user, and password fields should look like in the configuration file.

2. Common Issues: Provide a brief section on common issues users might face when configuring PostgreSQL, such as connection errors or permission issues, along with troubleshooting tips.

3. Verify Configuration Steps: Include a reminder for users to verify their PostgreSQL server is running and accessible before starting the application.

By enhancing these sections in the documentation, it will aid users in setting up their database correctly and reduce confusion during the initial setup.
