How to log database changes during an upgrade?

Why would you need to log them? They’re defined in the code itself.

Look at wp-admin/includes/upgrade.php. Every version that changes the DB has a function defined that does the job. The changes made for version 3.4 are defined in the upgrade_340() function. The changes made for 3.3 are defined in the upgrade_330() function. And so on.
