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

# 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"
