Answer 1

I ended up here after attempting to follow Ryan Bate's tutorial on deploying to AWS EC2 with rubber. Here is what happened for me: We created a new app using "

rails new blog -d postgresql

Obviosuly this creates a new app with pg as the database, but the database was not made yet. With sqlite, you just run rake db:migrate, however with pg you need to create the pg database first. Ryan did not do this step. The command is rake db:create:all, then we can run rake db:migrate

The second part is changing the database.yml file. The default for the username when the file is generated is 'appname'. However, chances are your role for postgresql admin is something different (at least it was for me). I changed it to my name (see above advice about creating a role name) and I was good to go.

Hope this helps.
