我是靠谱客的博主 朴素鞋垫,这篇文章主要介绍Conventions,现在分享给大家,希望可以做个参考。

The following conventions are used in the synopsis of a command: brackets ([ and ]) indicate optional parts. (In the synopsis of a Tcl command, question marks (?) are used instead, as is usual in Tcl.) Braces ({ and }) and vertical lines (|) indicate that you must choose one alternative. Dots (...) mean that the preceding element can be repeated.

Where it enhances the clarity, SQL commands are preceded by the prompt =>, and shell commands are preceded by the prompt $. Normally, prompts are not shown, though.

An administrator is generally a person who is in charge of installing and running the server. A user could be anyone who is using, or wants to use, any part of the PostgreSQL system. These terms should not be interpreted too narrowly; this book does not have fixed presumptions about system administration procedures.

 

在命令的语法概要中使用以下约定:括号[]之间的表示可选部分,{}和|表示参数必选一个。...表示可以重复前面的参数。

为了方便查看,SQL命令以=>提示,shell命令以$提示。当然,一般情况下,实际执行的时候,提示是不会显示的。

管理员的职责一般是安装和管理服务端。用户可以是在用、或者是想用PostgreSQL系统某一部分的任何人。

这些术语不应该狭义的理解。本文档并没有对系统管理过程做固定的臆断。
