No listFields() method in Postgre connection

Error: Call to undefined method CodeIgniter\Database\Postgre\Connection::listFields()

At BASEPATH/Database/BaseConnection.php at line 1263, method fieldExist() calls listFields() wich is absent

     * Determine if a particular field exists
     *
     * @param   string
     * @param   string
     * @return  bool
     */
    public function fieldExists($fieldName, $tableName)
    {
        return in_array($fieldName, $this->listFields($tableName));
    }

I found the way as follows:

• Change method fieldExists() in BaseConnection.php to call method getFieldNames() instead of listFields()

public function fieldExists($fieldName, $tableName)
    {
        return in_array($fieldName, $this->getFieldNames($tableName));
    }

Little changes ... ¡big joy!
