I am trying to use the constraints options:
- NOT ENFORCED
- DEFERRABLE
- INITIALLY DEFERRED
- NORELY
However it seems I am not able to use them successfully.
When I try to use them with PRIMARY KEYS (not sure if it is possible), I am not able to enforce any key.
And it also seems I cannot use them with other constraints:
How are we supposed to use this constraint option? Thank you
