尝试创建新数据库后，我的 PostgreSQL 10 服务器崩溃，无法重新启动

Question

我是 PostgreSQL 新手，在开始使用时遇到了很多问题。出于某种原因，当我尝试创建新数据库时，服务器崩溃并且无法重新启动。我做错了什么，如何解决这种情况？我还在使用安装在 Windows 10 操作系统上的 Ubuntu 18.04。

我一直在关注这个教程：https://www3.ntu.edu.sg/home/ehchua/programming/sql/PostgreSQL_GetStarted.html

事情是这样的：

postgres=# CREATE DATABASE courtney;
WARNING:  terminating connection because of crash of another server process
DETAIL:  The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory.
HINT:  In a moment you should be able to reconnect to the database and repeat your command.
server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

尝试重新启动时：

$ sudo service postgresql start
