Documentation not accurate in Database Forge Class

It only throws if it is in debug mode:

PHP Code:

    public function createDatabase(string $dbName, bool $ifNotExists = false): bool
    {
        if ($ifNotExists && $this->createDatabaseIfStr === null)
        {
            if ($this->databaseExists($dbName))
            {
                return true;
            }
            $ifNotExists = false;
        }
        
        if ($this->createDatabaseStr === false)
        {
            if ($this->db->DBDebug)
            {
                throw new DatabaseException('This feature is not available for the database you are using.');
            }

            return false;
        }
        elseif (! $this->db->query(sprintf($ifNotExists ? $this->createDatabaseIfStr : $this->createDatabaseStr, $dbName, $this->db->charset, $this->db->DBCollat))
        )
        {
            if ($this->db->DBDebug)
            {
                throw new DatabaseException('Unable to create the specified database.');
            }

            return false;
        }

        if (! empty($this->db->dataCache['db_names']))
        {
            $this->db->dataCache['db_names'][] = $dbName;
        }

        return true;
    } 


This is set in your Database config (e.g. .env, or app/Config/Database.php) and defaults to 'DBDebug'  => (ENVIRONMENT !== 'production')
