I fixed it.

Replace the line 40-41:

// SHOW INDEX emulation
		if( 0 === strpos( $sql, 'SHOW INDEX'))

to:

if ( 0 == strpos( $sql, 'SHOW FULL COLUMNS')) {
			$logto = 'SHOWCOLUMN';
			$pattern = '/SHOW FULL COLUMNS.+ [<code>]?(\w+)[</code>]?$/';
			preg_match($pattern, $sql, $matches);
			$table = $matches[1];
$sql = 'SELECT column_name as Field, data_type as Type, NULL as Collation, is_nullable as Null,
            \'\' as Key, \'\' as Default, \'\' as Extra, \'\' as Privileges, \'\' as Comment
            FROM information_schema.columns WHERE table_name =\''.$table.'\';';
        }
		// SHOW INDEX emulation
		elseif( 0 === strpos( $sql, 'SHOW INDEX'))

Now database upgraded successful.
