 On further discussion, fixing `db_version()` is going to be significantly
 more difficult than I initially thought. It's currently being used to
 compare against version numbers, which breaks for anything except vanilla
 MySQL. Other DB servers, such as MariaDB, Postgres, Drizzle, SQLite and
 SQL Server all have different version numbering.

 I suspect in the future we'll offer extended version information, but it
 would need to offer full information, rather than just a string.

 In the mean time, plugin developers can work around this with the

 if ( $wpdb->use_mysqli ) {
         $ver = mysqli_get_server_info( $wpdb->dbh );
 } else {
         $ver = mysql_get_server_info();


 Note that `use_mysqli` and `dbh` can indeed be accessed, as wpdb has a
 magic getter.
