	# This is a simple script that will handle the creation of principals on
	# the KDC, the creation of keytabs with appropriate permissions, and
	# the copying of keytabs to the appropriate locations. It's input is the
	# host-principal-keytab-list file that Ambari generates.
	#
	# This script MUST be run as root on the KDC node.

	These instructions are taken from: Keita's Blog - https://kkob.us/2016/01/09/homebrew-and-postgresql-9-5/

	1. Turn PostgreSQL off first, just in case:
	$ launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

	2. Update PostgreSQL itself:
	$ brew update && brew upgrade postgresql

	3. Make a new, pristine 9.5 database:
	$ initdb /usr/local/var/postgres9.5 -E utf8

	Key idea #1: Variable bindings in Rust "have ownership" of what they're bound to.
	let x = 5; // 'x' "OWNS" the value 5
	let v = vec![1,2,3,4,5]; // 'v' "OWNS" the vector datastructure which contains the values '1,2,3,4,5'
	Ownership is a serious matter - even functions "own" their parameters, so this WILL NOT compile:

	fn main() {
	fn somefunc(x: i32, v: Vec<i32>) -> i32 {
	// somefunc "owns" x and v once they are bound as parameters
	12
	}
