How to upgrade a Heroku PostgreSQL database to a new plan

I started a project on a Hobby Dev plan (free, limit 10,000 rows), and then later needed to upgrade it to Hobby Basic ($9/month, limit 10,000,000 rows).

After assigning the new database, I had two databases attached to the application. They looked something like this:

• HEROKU_POSTGRESQL_OLIVE (postgresql-dimensional-3321) Old, free-tier (Hobby Dev) database

You can use CodePipeline and CodeBuild to create a continuous deployment/integration pipeline for serverless applications build on AWS Lambda and Amazon API Gateway. This sample application is written in Go with the Gin framework and uses the eawsy API Gateway proxy shim: https://github.com/eawsy/aws-lambda-go-net

We initially detailed our methodology in this blog post: https://aws.amazon.com/blogs/compute/continuous-deployment-for-serverless-applications/

We have used the shim technology created by eawsy to run Golang applications inside AWS Lambda (https://github.com/eawsy/aws-lambda-go-shim) and created a container that can be used with CodeBuild as part of our original pipeline template.

The container is available on DockerHub and is called sapessi/aws-lambda-go18-codebuild:latest. To use this container, simply change the Image property of the CodeBuild project environment.

The pipeline template, sample app, buildspec and SAM files are attached to this gist.
