django psycopg2和postgresql插入錯誤

我無法將任何數據添加到我的數據庫。它允許我修改表中的條目，但任何會在數據庫中創建新行或新列的操作都會神祕地失敗。這裏是堆棧跟蹤：django psycopg2和postgresql插入錯誤

它工作正常，直到我將數據庫遷移到另一臺服務器。現在我有各種麻煩，我不確定要做什麼。另外，如果試圖向數據庫添加字段，這似乎也會發生在南方。奇怪的是，修改數據庫中的現有對象/列成功不會失敗。我真的不確定要做什麼，並且會喜歡任何幫助。

你正在使用的postgresql的版本是什麼？你能確認它的9.1嗎？ – 2012-04-26 19:22:48

PostgreSQL 8.1.23，Django要求9.1正確嗎？或者至少與psycopg2後端（我認爲psycopg是<9.1）。感謝您的洞察力，這正是我尋找的答案 – ecbtln 2012-04-26 19:43:19

8.1不支持RETURNING子句。因此，將您的數據庫版本升級到當前的穩定版本。

謝謝你的幫助 – 2012-06-28 00:25:09

8.1不支持插入對象的RETURNING ID，因此您需要禁用它。

from django.db import connection 
##just before insert statement 
connection.features.can_return_id_from_insert = False  
###some insert statement
