os x 上 postgresql 的 initdb 失败

Question

在我的 Mac 版本 10.12.5 上安装 postgres 10 时遇到问题。

我试过安装两种方式：

(1) Downloading Postgres.app
(2) `brew install postgresql`

并尝试为initdb手动运行这些命令的一系列变体：

$ initdb /Applications/Postgres.app/Contents/Versions/latest/bin/ver-10
$ initdb /usr/local/var/postgres -E utf8

全部产生相同的错误FATAL: could not create semaphores: Invalid argument 。

完整跟踪：

The files belonging to this database system will be owned by user "foo".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.UTF-8".
The default text search configuration will be set to "english".

Data page checksums are disabled.

我不确定FATAL: could not create semaphores: Invalid argument是什么意思。 我已经看到了很多与空间不足有关的其他答案，但不是这个。

提前致谢！

我必须删除通过 Brew 安装的 Postgres，然后重新安装 Postgres.app，然后重新启动计算机，然后打开应用程序并单击“初始化”修复它。
