今天我也遇到了同样的事。我通过使用——inserts命令转储来处理问题。

我所做的是:

1) pg_dump插入:

pg_dump dbname --username=usernamehere --password --no-owner --no-privileges --data-only --inserts -t 'schema."Table"' > filename.sql

2) PSQL(恢复转储文件)

psql "dbname=dbnamehere options=--search_path=schemaname" --host hostnamehere --username=usernamehere -f filename.sql >& outputfile.txt

注意1)确保添加outputfile可以提高导入的速度。

注2)在用psql导入之前，不要忘记创建具有完全相同名称和列的表。

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.

安装postgresql-(你的版本)-postgis-scripts

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。

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.
