[vitorfarias86]

Hi,

I'm newby in zabbix, and I've a problem
My users needs more space to write 'acknowledge text',
Is there any problem in increase the field in postgresql such as

ALTER TABLE acknowledges ALTER COLUMN message TYPE text;

and in monitoring.acknowledge.edit.php

   $form_list = (new CFormList())
        ->addRow(_('Message'),
                (new CTextArea('message'))
                        ->setWidth(ZBX_TEXTAREA_BIG_WIDTH)
                        ->setMaxLength(255)
                        ->setAttribute('autofocus', 'autofocus')
        );
