Try-Catch for Exception Handling

• 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.

You can loop through all posts, delete each post, and then remove any associated media files (attachments). Here's a complete script to achieve this:

<?php
// Load WordPress environment
require_once('/path/to/your/wp-load.php');

// Get all posts (any post type)
$args = array(
    'post_type'      => 'any', // 'any' retrieves all post types (posts, pages, custom post types)
    'post_status'    => 'any', // 'any' retrieves all post statuses
    'posts_per_page' => -1,    // Retrieve all posts
);

$all_posts = get_posts($args);

foreach ($all_posts as $post) {
    // Get the post ID
    $post_id = $post->ID;

    // Check if the post has attachments (media files)
    $attachments = get_attached_media('', $post_id);

    // Delete each attachment associated with the post
    foreach ($attachments as $attachment) {
        $attachment_id = $attachment->ID;
        // This deletes the file from the uploads directory and the database record
        wp_delete_attachment($attachment_id, true);
    }

    // Delete the post itself
    wp_delete_post($post_id, true); // true = force delete, bypass trash
}

echo 'All posts and their uploads have been deleted.';
