Anyone that has installed application running in the background from Homebrew, knows how to use launchctl that actually runs every application when the computer restarts. It is pretty straight forward task but most of the time you need to know the location of the .plist file that defines how to run it installed with homebrew.
Now there is a quicker path how to control them by simply adding following package to home-brew:
brew tap gapple/services
brew services list
brew services start postgresql
brew services stop postgresql
Which is much more easier and simpler than finding the right .plist file inside cellar folder of brew
