This PR is a possible start to adding 2 new relations:

  • relationOneToMaybeOne: |o--o|
  • relationManyToMaybeOne: }o--o|

The code makes use of the IsUnique and IsNullable properties of ColumnResult, however, in its current form, it can't differentiate between one column being unique vs multiple columns being unique (IsUnique is true for both).

As far as I can see, differentiating between individual unique columns vs multiple columns being unique together would require collecting additional info from the database and so would be a bigger change.
