Create a database on PostgreSQL via a command line

Question

I'm trying to create database in psql via CLI.

psql  -U postgres createdb portal

I kept getting

psql: warning: extra command-line argument "portal" ignored
psql: FATAL:  database "createdb" does not exist

What did I do wrong ?

Note

I'm not trying to queries any data.

在这里，我以用户vao身份连接到数据库postgres（始终存在）并db1在CLI...中创建数据库...第一个没有键的参数是数据库名称，因此在您的示例中createdb被解释为 dbname 以连接到...

请查看psql 的文档

Vaos-MacBook-Air:tts vao$ bash -c "psql -U vao postgres -c 'create database db1;'"
CREATE DATABASE
