postgresql-9.2 – 我的数据库在哪里发布了postgres？

postgres拒绝工作.我正在使用9.2和一个新手.

我创建了一个数据库.我列出了它不在那里？没有错误！它去了哪里？有没有创造过？

Password for user postgres: 
psql: FATAL:  database "test" does not exist

你有两个错误：

> createdb是一个操作系统命令,它不是sql命令.在psql中,您需要使用sql语句,即：CREATE DATABASE.有关详细信息,请参见手册：http://www.postgresql.org/docs/current/static/sql-createdatabase.html
>每个sql语句都需要以;终止.由于您没有这样做,您的声明未执行,因此您没有收到错误.有关详细信息,请参见手册：http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html
