launchctl 命令加载,卸载开机自动运行的服务,在 OS X 中,服务本身存储在 .plist 文件中(即 property list),这些文件的位置一般在 ~/Library/LaunchAgents/Library/LaunchAgents。可以使用 launchctl load $PATH_TO_LISTunload them with launchctl unload $PATH_TO_LIST 命令来加载/卸载他们。加载就是允许这个程序开机执行,卸载反之。

如果你使用 Homebrew 安装过 mysql 那么下面的安装后提示你可能比较熟悉

To have launchd start mysql at login:
   ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
Then to load mysql now:

PostgreSQL index naming convention to remember

The standard names for indexes in PostgreSQL are:

{tablename}_{columnname(s)}_{suffix}

where the suffix is one of the following:

  • pkey for a Primary Key constraint;
  • key for a Unique constraint;
  • excl for an Exclusion constraint;
  • idx for any other kind of index;
