Thread:Project:Support desk/MySQL user for MediaWiki: What rights?/reply (3)

You can set a DBadminuser (with more rights) for the maintance scripts:
 * Manual:$wgDBadminuser
 * Manual:$wgDBadminpassword

Don't know if that user will handle upgrade.

One more thing: On windows, the installer asks for the root password of the MySQL root account.
