Following https://github.com/instructure/canvas-lms/wiki/Quick-Start I ran into some problems.  Here's what I did to work around them.

I am installing on my development computer, running Ubuntu 13.10.

dpkg --get-selections | egrep -i "postgresql"
postgresql					install
postgresql-9.1					install
postgresql-9.1-postgis				deinstall
postgresql-client-9.1				install
postgresql-client-common			install

## reduce_precision_of_datetime_columns.rb
# Change all datetime columns to have a precision of 0, to match the default precision of these
# columns in MySQL.
#
# This is useful if you migrate a database from MySQL to PostgreSQL and don't need the extra
# microsecond precision (precision: 6) that is the default in PostgreSQL
# (see http://www.postgresql.org/docs/9.2/static/datatype-datetime.html).
#
# Before:
#  > some_record.created_at.strftime('%Y-%m-%d %H:%M:%S.%N')
# => "2013-07-25 11:49:33.270032000"

## form_helper_extensions.rb
# Extensions to gems/actionpack-3.2.13/lib/action_view/helpers/form_helper.rb

=begin
A version of InstanceTag.value_before_type_cast that returns a string in ISO-8601 format for Date columns.

The original behavior of value_before_type_cast was to return the Date object itself. But the default to_s on a Date returns a string like "June 5, 2013".

However, HTML5 date input fields expect their values to be in ISO-8601 format ("2013-06-05") and won't recognize the value if it is in some other format.

This makes it so you can simply do this:
	require 'facets/hash/recurse'

	# Usage:
	# expect(actual).to match_hash(expected)
	#
	RSpec::Matchers.define :match_hash do \|expected\|
	match do \|actual\|
	# Sort hashes before comparing so that the diff only shows actual changes between keys and
	# values.
	actual = actual.recurse {\|h\| h.sort_by {\|k,v\| k.to_s }.to_h }
	begin
	require 'bundler/inline'
	rescue LoadError => e
	$stderr.puts 'Bundler version 1.10 or later is required. Please update your Bundler'
	raise e
	end

	gemfile(true) do
	source 'https://rubygems.org'
	gem 'rails', '5.1.4'

	class << self
