Outdated note: the process is a lot easier now: after you brew install postgresql you can initialize or stop the daemon with these commands: brew services start postgresql or brew services stop postgresql.

new out put may look like

To have launchd start postgresql now and restart at login:
  brew services start postgresql
Or, if you don't want/need a background service you can just run:
  pg_ctl -D /usr/local/var/postgres start

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.
