Postgres Cheatsheet

This is a collection of the most common commands I run while administering Postgres databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Postgres has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.

Setup

installation, Ubuntu

http://www.postgresql.org/download/linux/ubuntu/ https://help.ubuntu.com/community/PostgreSQL

	#!/bin/bash

	set -e

	# This command reads the file repos.json and clones or pulls
	# git repositories in particular branches. If there are local
	# edits in these repos, they are stashed and reapplied.

	If you are running a large website where you will need to test new features on a seperate url before pushing them live then the following instructions are for you ;)

	For this example imagine your url is apple.com and you want a development/staging site on a subdomain which is dev.apple.com

	#Setup#
	1. First thing you'll want to do is go ahead and create your website in plesk and add the subdomain dev.apple.com at the same time.
	2. ssh into the server e.g. $ ssh username@ipaddress
	3. Once logged in cd into the private directory (this will be where all git repos are stored) e.g. $ cd ~/private
	4. Create the main repo e.g. $ git init --bare apple.git
	5. Now to clone this new repo on your local machine. $ git clone ssh://username@ipaddres/~/private/apple.com

	// === Arrays

	var [a, b] = [1, 2];
	console.log(a, b);
	//=> 1 2


	// Use from functions, only select from pattern
	var foo = () => [1, 2, 3];
