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

AutoTA Example

• A series of transformer models that embed your course documents, search for them when you ask it a question, and construct a reply in coherent english using a text2text generator.
• Based on the work done by deepset.ai in their Haystack library.
• As the notebook preview does not always load on GitHub, click here for the Colab notebook / demo. Instructions are provided on what to edit to use the notebook both in simple cases (i.e. just changing the questions) to adapting the notebook for other purposes.

Example: The model's explanation of K-Means

question to model: What is the k-means algorithm?
