Thanks for the fix. It wasn't a typo, just a document that hadn't been updated in many years. That section of the document was added 4 years ago:

https://trac.macports.org/wiki/howto/MAMP?action=diff&version=54&old_version=53

The table names used to use just a single underscore, before phpMyAdmin had the double-underscore feature. A decade ago, I suggested to the developers of phpMyAdmin that they use the double-underscore in the default table names; they finally implemented that suggestion last year:

https://sourceforge.net/p/phpmyadmin/feature-requests/628/

I don't really see why we have duplicate documentation for how to configure phpMyAdmin; I don't see why we don't just refer users to the upstream documentation.
