Support for DEFERRABLE INITIALLY DEFERRED was added in . It would be great if it could be extended to the implicit Unique constraint generated by OneToOneField, say, by adding an argument:
OneToOneField(OtherModel, defer=models.Deferrable.DEFERRED)

Not sure we should do that as it seems pretty niche.

I guess an alternative API could be to allow passing a UniqueConstraint to the unique kwarg like we've discussed doing to the Field.index one.


OneToOneField(OtherModel, unique=UniqueConstraint(defer=models.Deferrable.DEFERRED))
