Should "Backing Up with SQL" in "Creating tables and modifying data" be moved to the top of the episode:
https://librarycarpentry.org/lc-sql/09-create/index.html
In other words, before you make changes to your database... make sure you back up and version your database. Instead of "Be very careful when doing this: if you drop the wrong table, hope that the person maintaining the database has a backup, but it’s better not to have to rely on it."
I also wonder if this should be an exercise, that we can highlight backing up your SQL and that versioning is an option with the caveats. Instead of the exercise we can include the action to dump the database and save it with the ISO 8601 date and name?
