Django轉移到PostgreSQL無法導入燈具，陳述數據太長

我正在從使用SQLite3轉換到PostgreSQL，並希望我可以使用我一直用來填充SQLite3的燈具填充數據庫。但是，我得到這些錯誤：Django轉移到PostgreSQL無法導入燈具，陳述數據太長

$ python manage.py loaddata fixtures/core.json fixtures/auth.json

我從來沒有使用過的任何數據長度錯誤，我沒有改變數據庫交換機之間的機型。 PostgreSQL正在運行utf8。有沒有辦法確切地看到哪些json值失敗，以便我可以更新相應的模型？任何想法，爲什麼值在SQLite中工作，但在PostgreSQL失敗？
