* NOTE:
* MS SQL doesn't support recursive foreign key constraints, nor having multiple foreign key constraints to the same
* related table. This means that about half of the above constraint triggers won't be available in MS SQL. To avoid
* confusion in what's there and what isn't, we'll skip the on-delete / on-update triggers altogether in MS SQL.
