When an `IntegrityError` is raised, the user receives a cryptic error
message which doesn't provide much valuable information in order to
solve the problem.
However, such an error is raised in 3 cases:
1. A mandatory field is not provided at creation/update.
2. The deletion of a record makes a mandatory Many2one field NULL on a
referenced table (`ON DELETE SET NULL` on a not nullable field).
3. The deletion of a record raises a `ON DELETE RESTRICT` foreign-key
constaints.
In the first and second cases, we provide the table and field on which
the `NOT NULL` constaint is raised. We also suggest to archive the
record in case of a deletion.
In the third case, we provide the table and the constraint raised. We
also suggest to archive the record.
Notes:
- The IDs of the records causing the issue is not provided since the
information is not provided by PostgreSQL.
- Although cases 2 and 3 have a different root cause, the error
message raised is very similar. Indeed, from an end-user perspective
the solution is identical: archive the record. Another solution would
also be to manually edit the records raising the error, but most of
the time this is not an option: these records are locked and cannot be
edited anymore.
