* On mysql/mariadb the column is able to store 65535 bytes.
|
|
*
|
|
* To create a column with type longtext length must be null (or an integer bigger than 16777215):

* Length option is only relevant for MySQL/MariaDB. Postgre, Oracle and Sqlite don't have a
|
|
* concept like tinytext, mediumtext, text and longtext.

* Postgre: https://www.postgresql.org/docs/9.1/datatype-character.html

* To make it worse our doctrine version (3.1.6 for F7cloud 24) is missing the logic to detect
