Details

Check for warnings after DB queries and throw an exception if an unacceptable warning is detected.

This setting is only used if $wgLBFactoryConf['class'] is set to '\Wikimedia\Rdbms\LBFactorySimple' and $wgDBservers is an empty array. Otherwise, the 'strictWarnings' parameter of the server array must be set to achieve the same functionality.
