1) backup production database:
	heroku pgbackups:capture --expire --remote production

2) obtain url string to backup from step 1:
	heroku pgbackups:url --app production_app_name --remote production_app_branch_name

3) transfer backup from production to staging app:
	heroku pgbackups:restore DATABASE 'production_app_backup_url_string_from_step_2' --app production_app_name --app staging_app_branch_name
