构建 Postgres 容器时修改用户密码出错

安装
1

在容器中成功安装 PostgreSQL 后，启动脚本会尝试更改 discourse 用户的密码。但是，我收到了这个错误：

Pups::ExecError: su - postgres -c 'psql discourse' failed with return #<Process::Status: pid 100 exit 141>
Location of failure: /usr/local/lib/ruby/gems/3.2.0/gems/pups-1.2.1/lib/pups/exec_command.rb:132:in `spawn'
exec failed with the params {"stdin"=>"alter user discourse with password 'redacted';\n", "cmd"=>"su - postgres -c 'psql discourse'", "raise_on_fail"=>true}
bootstrap failed with exit code 141
** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one.

看起来 PostgreSQL 在执行此命令时并未运行，因此在管道破裂时失败。我的 postgres.yml 是基于 data.yml 示例文件配置的，所以我不太确定我哪里做错了。有什么建议吗？

您好，之前的日志中没有明显问题，但在容器日志中我注意到此消息：

即使注释掉了 after_postgres 密码修改项，这也会导致容器崩溃，这就是出现管道破裂的原因。
