I had the same error message pop up when trying to datadump.

For what it's worth: in my case, I had some things messed up in my database. Some postgres tables not linked to models in django, and some models in django that had no tables in postgres. When I removed the tables not linked to models and the models not linked to tables, datadump went fine.
