7600	"bug in postresql sequence_reset_sql causes ""loaddata"" to fail for derived class with alternate primary key"	Shaun Cutts	nobody	"django.db.backends.postgresql.operations.sequence_reset.sql loops over ""fields"" when searching for primary keys:

{{{
            for f in model._meta.fields:
}}}

But it should loop only over fields specific to that class:
{{{
            for f in model._meta.local_fields:
}}}

With this fix, loaddata works on such derived models.
