Question

“psql \ dt information_schema”我正在编写此命令以查看所有表及其询问的列表“”用户information_schema的密码：“”我应该提供哪个密码，I meadn I m提供postgres作为密码。

Answer 1

你用下面的命令做什么：

psql \dt information_schema 

是启动PSQL并通过名为“INFORMATION_SCHEMA”作为用户名与连接。

必须输入\dt information_schema命令后您已经启动psql并且您看到psql提示符后。

如果您想直接在命令行中运行，而无需等待psql的提示，则需要使用-c开关：

psql -c "\dt information_schema.*" postgres postgres 

所有参数和他们预计的排列顺序当您运行psql --help或看看手册：

下面是一个简单的控制台会话将告诉您如何做到这一点：

 
c:\>psql postgres postgres 
Password for user postgres: 
psql (9.0.4) 
Type "help" for help. 

postgres=# \dt information_schema.* 
         List of relations
