Create Postgres Database Reference
I always forget the commands for creating a postgres database from EC2, so I made a reference so that I don't have to figure it out again next year. The main thing that always throws me off is that the createdb command isn't run in the psql command or have a postgresql related command name.
Install postgresql-client
apt-get install postgresql-client
Create Database
createdb database_name -U username -h your_rds_endpoint.us-east-1.rds.amazonaws.com
