We all know the drill with MySQL and Django.  You have a dev database, probably compressed, and you need to roll it out so your server's in a "pristine" state before you start running migrations and adding stuff.  And the routine typically looks something like this: gzip -dc dev_database.gz | mysql -u djanguser -p djangodb.  It is also perfectly legitimate (and less error-prone) with Django to do this instead: gzip -dc dev_database.gz | ./manage.py dbshell.

Yes, that's painfully obvious. But sometimes, we miss the painfully obvious.
