Setup amazon linux server (free tier)

• From Amazon's EC2 page, go to Launch Instance
• Choose an Amazon Linux 64-bit server and continue
• Select t2.micro (this is the free tier)
• Continue to the Add Storage page and adjust this up to 30GB if you're so inclined (default is 8GB, which is plenty)
• Tag your instance with a name like "notebook"

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 postgresql@9.6
brew unlink postgresql@9.6
brew link postgresql
