我尝试了各种（虽然我理解它们并且认为我有正确的组合）：
- 编码
- header/没有header
- 不同的引用/转义组合
- 我从列列表中删除了 id 字段，因为它不在 csv 中
下载的数据是一个大样本，所以我可以想象我需要调整一些东西，但是我不知道错误消息中没有给出详细信息。
除 id 外，每个字段都允许为 null。

不要使用 pgAdmin 调试它，因为它会向您隐藏错误消息。您需要单击“更多详细信息...”，然后通过拖动一个角来展开对话框，然后您会看到错误消息。
使用 psql，我得到：
ERROR: extra data after last expected column
CONTEXT: COPY flights, line 2: "2020,1,1,17,5,2020-01-17,"B6",20409,"B6","N661JB","942",14027,1402702,34027,"PBI","West Palm Beach/P..."
确实，每行末尾都有一个逗号。如果我删除那个逗号，我会收到一条不同的错误消息：
ERROR: invalid input syntax for type integer: "6.00"
CONTEXT: COPY flights, line 2, column taxiin: "6.00"
所以你看，错误消息很有帮助。使用 psql 调试问题。一旦一切正常，您可以恢复到 pgAdmin。
我正在尝试将 csv 导入 pgadmin4。
我一直收到错误代码 1，但没有详细信息。
