• This code retrieves the DATABASE_URL from the environment.
• If DATABASE_URL starts with postgres://, it replaces it with postgresql+psycopg2://.
• The db instance is initialized with SQLAlchemy(app) for use with SQLAlchemy ORM.
• The replacement of "postgres://" with "postgresql+psycopg2://" is necessary because of a compatibility issue between the URI format provided by Heroku and the URI format expected by SQLAlchemy.

• 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.
