fixture loading silently failing on postgresql

[sandro@…]

Attached simple case shows 2 models, connected by a simple foreign_key and a fixture. Loading the fixture against PostgreSQL, will silently fail. Log from PostgreSql and console are also attached.

The key is the fact that the foreign key does not pout to an id but to another field.
It the model is changed to point to the id the fixture is loaded.

[Moreover if a spelling error is present in the model, no message is issued and in the console the log says no fixture is found]

[anonymous]

the system raises InternalError trying to attach the file, so I put it here:

(In [5232]) Fixed #4288 -- Modified serializers to pay attention to the to_field attribute on ForeignKeys. Thanks to Sandro Dentella for the report and the helpful test case.
