对我来说，与源数据库不同的是ENCODING和LOCALE。 一旦我放弃了目标DB并重新创建它，它就可以正常工作。

我的解决办法是:

psql -U your_user your_db < your.file.here.sql  2>&1|more

这样我就可以读取错误消息

我希望这能对大家有所帮助。

当我试图从二进制pg_dump恢复时，我收到了相同的错误消息。我简单地使用pg_restore来恢复我的转储，并完全避免\N错误，例如。

pg_restore -c -F t -F your.backup.tar

开关说明:

-f, --file=FILENAME      output file name
-F, --format=c|d|t       backup file format (should be automatic)
-c, --clean              clean (drop) database objects before recreating

Adding my resolution, incase it helps anyone. I installed postgis but the error wasn't resolved. The --inserts option was not feasible as I had to copy a big schema having tables with thousands of rows. For the same database I didn't see this issue when pg_dump and psql (restore) were run on mac. But the issue came when pg_dump was run on linux machine, the dump file copied to mac and tried for restore. So I opened the dump file in VSCode. It detected unusual line terminators and gave option to remove them. After doing that the dump file restore ran without the invalid command \N errors.

在我的例子中，问题是在我的目标计算机上缺少磁盘空间。简单地增加本地存储为我解决了它。

希望这能帮助到一些人;)

可以使用INSERTS语句和——INSERTS参数生成转储。
