"Scar Tissues Make Relationships Wear Out"

04/26/2103. From a lecture by Professor John Ousterhout at Stanford, class CS142.

This is my most touchy-feely thought for the weekend. Here’s the basic idea: It’s really hard to build relationships that last for a long time. If you haven’t discovered this, you will discover this sooner or later. And it's hard both for personal relationships and for business relationships. And to me, it's pretty amazing that two people can stay married for 25 years without killing each other.

	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
