我正在尝试使用以下命令在 PostgreSQL 中创建一个数据库：

createdb -E UTF8 aws-inventories

该命令没有错误。但是当我列出数据库时，新数据库不存在：

postgres-# \l
                                                     List of databases
       Name        |  Owner   | Encoding |          Collate           |           Ctype            |   Access privileges

                   |          |          |                            |                            | postgres=CTc/postgres
 template1         | postgres | UTF8     | English_United States.1252 | English_United States.1252 | =c/postgres          +
                   |          |          |                            |                            | postgres=CTc/postgres
(6 rows)

如果我尝试更改为该新数据库，它会告诉我它不存在：

postgres-# \c aws-inventories
FATAL:  database "aws-inventories" does not exist
Previous connection kept

CREATE DATABASE我也用命令试过这个。我得到了同样的结果：

postgres=# CREATE DATABASE aws-inventories
postgres-# \l
                                                     List of databases

 template1         | postgres | UTF8     | English_United States.1252 | English_United States.1252 | =c/postgres          +
                   |          |          |                            |                            | postgres=CTc/postgres
(6 rows)


postgres-# \c aws-inventories
FATAL:  database "aws-inventories" does not exist
Previous connection kept

在 PGAdmin4 中执行相同的命令，我确实得到了一个错误：

createdb aws-inventories
ERROR:  syntax error at or near "createdb"
LINE 1: createdb aws-inventories
        ^
SQL state: 42601
Character: 1**strong text**

CREATE DATABASE aws-inventories
ERROR:  syntax error at or near "-"
LINE 1: CREATE DATABASE aws-inventories
                           ^
SQL state: 42601
Character: 20

我在 PostgreSQL 13。为什么 Postgres 拒绝创建这个数据库？
