Jira issue originally created by user chrisguitarguy:
Column::visit tries to Doctrine\DBAL\Schema\Visitor\Visitor::accept
It doesn't look like Visitor actually has an accept method.
The method needed seems to be Visitor:: acceptColumn, but Column itself doesn't seem to be aware of it's parent table in any way.
Comment created by @beberlei:
Removed the method, the Table#visit() method is responsible for this.
