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.

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 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;

sudo -u postgres createuser --superuser $USER

sudo -u postgres createdb $USER

这绝对适合你。

我用docker-compose做了健康检查。

healthcheck:
  test: ['CMD-SHELL', 'pg_isready']
  interval: 5s
  timeout: 5s
  retries: 5

如果你也有这样的更改用户:

healthcheck:
  test: ['CMD-SHELL', 'pg_isready -U postgres'] # <<<---
  interval: 5s
  timeout: 5s
  retries: 5

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。
