"""
Script to run Alembic migrations for the task management application.

This script demonstrates how to run the database migrations when PostgreSQL is available.

To run migrations in a real environment:

1. Make sure PostgreSQL is running:
   docker-compose up -d db

2. Run this script:
   python run_migrations.py

Or run directly with Alembic:
   cd backend
   alembic upgrade head
