如何让自己成为postgresql的超级用户？
我一直在尝试创建一个数据库,并且我不断收到以下错误:
createdb:数据库创建失败:错误:拒绝创建数据库的权限
我猜这是因为我不是超级用户,但我不知道什么是错的.这是我做的:
> sudo su postgres
> postgres@precise64:/xxx/xxx/projectfile$createuser -P
> Enter name of role to add: vagrantUser
> Enter password:
> Enter it again:
> Shall the new role be a superuser? (y/n) y
> postgres@precise64:/vagrant/django_projects/mblog$ psql -U vagrantUser template1
> psql: FATAL: Peer authentication failed for user "vagrantUser"
> postgres@precise64:/vagrant/django_projects/mblog$ exit
> (venv)vagrant@precise64:/vagrant/project$:psql template1
> template1 =# \q
> (venv)vagrant@precise64:/vagrant/project$:createdb mydb
我收到以下错误:
createdb:数据库创建失败:错误:拒绝创建数据库的权限
请帮助
<?php
$tiger = array ("orange", "white");
$cat = array ("black", "white", "brown");
$fruit = array ("purple", "red", "green", "brown");
?>
如何输出如下内容:
orange : tiger
white : tiger + cat
black : cat
brown : cat + fruit
purple : fruit
