cubicweb #5560601 [sqlserver] crash on column alteration when there are related unique together constraints [validation pending]

The multi column constraints are implemented in sqlserver with a view on top of which there is a unique index.
When changing a column type (e.g. null -> not null, size of a text column), sqlserver complains that there are "dependant objects" (typically the views) and that it cannot proceed.

We probably need to drop unique together constraints and rebuild them if such a column change occurs.
