Your system is now running PostgreSQL with PostGIS. 
You should now run "aws configure" to set up the AWS CLI.   
Afterwards, you should stop this instance and create an AMI.

I got a conflict between postgresql-devel and libpq-devel when running a fresh install. Changing line 29 to the following fixed it.

Thank you, this has been incorporated.

Note to others - while this includes the PostGIS extension, it does not include other common (e.g. fuzzystrmatch) extensions. To add them, simply run: sudo yum install -y postgresql-contrib
