PostgresQuerySet.insert assumes the existence of an 'id' field

[PeterJCLaw]

It should probably use pk instead so that it can be used with models whose primary keys are named other than id.

[elnygren]

Yup, .insert is broken if your Model uses something else than 'id' as a primary key.

For django devs, a quite common usecase might be

class Profile(...):
  user = OneToOneField(User, primary_key=True, ....)
