FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

	// Mozilla User Preferences
	// To change a preference value, you can either:
	// - modify it via the UI (e.g. via about:config in the browser); or
	// - set it within a user.js file in your profile (create it if it doesn't exist).

	# Put this function to your .bashrc file.
	# Usage: mv oldfilename
	# If you call mv without the second parameter it will prompt you to edit the filename on command line.
	# Original mv is called when it's called with more than one argument.
	# It's useful when you want to change just a few letters in a long name.

	After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work.
	The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0."

	Database files have to be updated before starting the server, here are the steps that had to be followed:

	# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default
	brew unlink postgresql
	brew install [email protected]
	brew unlink [email protected]
	brew link postgresql
