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

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.

按照以下步骤让postgres工作。

在终端中，使用以下命令找到应用程序支持文件夹。 /Users/[用户名]/库/应用程序支持 删除应用程序Postgres。 重新安装应用程序，它应该工作得很好。

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

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。
