Windows用户:psql -U postgres

然后你应该看到PostgreSQL的命令行界面:postgres=#

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。

我把它安装在macOS上，必须:

cd /Applications/Postgres.app/Contents/Versions/9.5/bin
createuser -U postgres -s YOURUSERNAME
createdb YOURUSERNAME

对于使用docker并正确遵循官方文档说明的用户，如果仍然遇到此问题，请重新启动窗口并重试。

sudo -u postgres createuser --superuser $USER

sudo -u postgres createdb $USER

这绝对适合你。

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.
