我有同样的问题，我创建了一个新的数据库，并得到无效的命令\N恢复与psql。 我通过设置与旧数据库相同的表空间来解决这个问题。

例如，旧数据库备份有表空间“pg_default”，我给新数据库定义了相同的表空间，上面的错误已经消失了!

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。

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。

大多数时候，解决方案是安装postgres-contrib包。

In my recent experience, it's possible to get this error when the real problem has nothing to do with escape characters or newlines. In my case, I had created a dump from database A with pg_dump -a -t table_name > dump.sql and was trying to restore it to database B with psql < dump.sql (after updating the proper env vars, of course) What I finally figured out was that the dump, though it was data-only (the -a option, so that the table structure isn't explicitly part of the dump), was schema-specific. That meant that without manually modifying the dump, I couldn't use a dump generated from schema1.table_name to populate schema2.table_name. Manually modifying the dump was easy, the schema is specified in the first 15 lines or so.
