Type BIT not supported by Typo3/Doctrine DBAL (working with alternative DB)
When using the Typo3 API with an alternative database, a table contains a column with type BIT but this type is not supported by Typo3/Doctrine DBAL, it results with the following message (see attachement) :
Unknown database type bit requested, Doctrine\DBAL\Platforms\MySQL57Platform may not support it.
While Doctrine/DBAL allowed to add custom data type, I didn't find a way with Typo3 (hook, config file) to add a custom datatype.
It should be possible with Typo3 to add a custom data type and may be better, Typo3 should have BIT type as a native type.
