• When you provision a PostgreSQL database on Heroku, it sets an environment variable called DATABASE_URL with the connection string for your database.
• This URI uses the format postgres://.

• SQLAlchemy (especially when using the psycopg2 driver for PostgreSQL) requires the URI to be in the format postgresql+psycopg2://.
• This prefix specifies the dialect (postgresql) and the driver (psycopg2) explicitly, which SQLAlchemy uses to establish the connection.

• Backup: Make sure you have a backup of your database and uploads folder before running this script.
• Use on a staging site: Test it on a staging environment before running on a live site, as it will permanently delete all posts and their uploads.

This script will ensure that both the posts and their associated media files are removed from the WordPress database and the filesystem.

To enable all error debugging in PHP, you can use the following PHP code snippet. This will display all errors, warnings, and notices:

<?php
// Turn on all error reporting
error_reporting(E_ALL);

// Display errors
ini_set('display_errors', 1);

// Optionally, you can log errors instead of displaying them
// ini_set('log_errors', 1);
// ini_set('error_log', '/path/to/php-error.log');

echo "Error reporting is enabled.";
?>

Run the server using Node.js:

   node index.js
