*
* 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
* Oracle: https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlqr/Data-Types.html#GUID-219C338B-FE60-422A-B196-2F0A01CAD9A4
* Sqlite: https://www.sqlite.org/datatype3.html / https://www.sqlite.org/limits.html
*
* To make it worse our doctrine version (3.1.6 for Nextcloud 24) is missing the logic to detect
* that the column length changed: https://github.com/doctrine/dbal/issues/2566
