PostgreSQL EDB安装程序的安装后步骤失败

Question

我正在使用Ubuntu Budgie 17.10 64bit。 尝试按EDB installer安装PostgreSQL 9.6时，它在post-install step上失败：

以下是日志文件中出现问题的部分。

Initialising the database cluster (this may take a few minutes)...
Executing /opt/PostgreSQL/9.6/installer/server/initcluster.sh "postgres" "postgres" "/opt/PostgreSQL/9.6" "/opt/PostgreSQL/9.6/data" 5432 ru_UA.utf8
Script exit code: 1

Script output:
 Failed to initialise the database cluster with initdb

Script stderr:

Problem running post-install step. Installation may not complete correctly
 The database cluster initialisation failed.

备注：

• 安装程序以root权限启动（如果没有，则会在启动时引发错误）。
• 安装失败后，/opt/PostgreSQL/9.6目录存在。

如何在没有EDB安装程序的情况下完成群集初始化？ 如何修复安装程序？ 报告EDB安装程序问题的正确方法是什么？
