Column image in catalog_product_flat

[OleKh]

After upgrade from v2.3.5 to v2.4.0 there is no column "image" in catalog_product_flat tables. In database for v.2.3.5 the column exists but it is not clear if it was created as system attribute.

Is it possible to add product attribute "image" into catalog_product_flat table as system attribute? 

vendor/magento/module-catalog/etc/catalog_attributes.xml

<group name="unassignable">
    <attribute name="image" />
    ...
</group>

Try this code instead :

$installer = $this;
$installer->startSetup();
$installer->getConnection()
        ->addColumn($installer->getTable('sales/quote_item'), 'customized_product_solitaire', array(
            'type' => Varien_Db_Ddl_Table::TYPE_INTEGER,
            'nullable' => false,
            'length'    => 1
        ));
$installer->getConnection()
          ->addColumn($installer->getTable('sales/order_item'), 'customized_product_solitaire', array(
            'type' => Varien_Db_Ddl_Table::TYPE_INTEGER,
            'nullable' => false,
            'length'    => 1
        ));
