Question

pg_dump -C -h localhost -U user_name database_name | psql -h 10.590.8.46 -U user_name database_name

我正在尝试将数据库转储到linux上的远程服务器，这是我不断得到的错误：

pg_dump: [archiver (db)] connection to database "database_name" failed:   
FATAL:  invalid command-line argument for server process: -I
HINT:  Try "postgres --help" for more information.

Answer 1

我可以重现此行为的唯一方法是设置PGOPTIONS环境变量：

export PGOPTIONS=-I

检查是否设置了该变量，如果是，则使用

取消设置

unset PGOPTIONS

Answer 2

您可以查看此帖子pg_dump postgres database from remote server

从远程转储数据库的命令是

ssh user@remote_machine "pg_dump -U dbuser -h localhost database_name " \
 >> backup_file_on_your_local_machine.sql
