当我运行导入时，在上面的屏幕上

\i C:<path>/file.sql with delimiter \n我得错了命令\ n 我也试过了

`\i C:<path>/file.sql delimiter \n`
`\i C:<path>/file.sql`

任何人都可以告诉我，如何让这个数据库进入服务器。帮助赞赏。感谢

Answer 1

通常，您可以在包含SQL文件之前在\set ON_ERROR_STOP中发出psql，以便在第一个错误处停止并且不会被后续错误淹没。

尝试复制到不存在的表时，COPY失败，其后的所有数据都被拒绝，并带有大量错误消息。

看看转储的开头，确实存在一些问题。

它创建了一个名为bensonsorderlystats_call的表，但随后将postgres的所有权赋予另一个不应该存在的public.stats_call。

然后它尝试将数据复制到名为stats的表中，该表也从未创建过，假设您正在恢复到空数据库中。

看起来好像有人手动编辑了转储并搞砸了。

Answer 2

尝试psql -U username -f dump.sql database_name。
