遵循以下步骤，它将为你工作:

run msfconsole type db_console some information will be shown to you chose the information who tell you to make: db_connect user:pass@host:port.../database sorry I don't remember it but it's like this one then replace the user and the password and the host and the database with the information included in the database.yml in the emplacement: /usr/share/metasploit-framework/config you will see. rebuilding the model cache in the background. Type apt-get update && apt-get upgrade after the update restart the terminal and lunch msfconsole and it works you can check that by typing in msfconsole: msf>db_status you will see that it's connected.

在尝试了许多其他人的解决方案后，都没有成功，这个答案最终帮助了我。

简而言之，跑步

sudo -u postgres createuser owning_user

创建名为owning_user(在本例中为h9uest)的角色。在此之后，您可以在终端上运行rake db:create，使用您设置的任何帐户名，而无需进入Postgres环境。

对我来说，像将端口从5432更改为5433这样简单的操作就可以了。

sudo -u postgres createuser --superuser $USER

sudo -u postgres createdb $USER

这绝对适合你。

sudo su - postgres

psql template1

在PGSQL上创建具有“超级用户”权限的角色

CREATE ROLE username superuser;
eg. CREATE ROLE demo superuser;

然后创建用户

CREATE USER username; 
eg. CREATE USER demo;

为用户分配权限

GRANT ROOT TO username;

然后启用该用户登录，这样你就可以从普通的$ terminal运行:psql template1:

ALTER ROLE username WITH LOGIN;

使用——no-owner——no-privileges标记转储和恢复

e.g.

Dump - pg_dump——no-owner——no-privileges——format=c——dbname=postgres://userpass:username@postgres:5432/schemaname > /tmp/full.dump

恢复- pg_restore——no-owner——no-privileges——format=c——dbname=postgres://userpass:username@postgres:5432/schemaname /tmp/full.dump
