> when you upgrade such extensions (that have their own database objects) you should run update.php

When you update the extension; that's clear. Your first statement made it sound like you update MediaWiki and do not change anything with an extension and out of a sudden the extension wants to change the database. I do not know of any case, where that happens. Good that you clarified this.
