Using PostgreSQL functions to call an API with Supabase

From the video description

Functions are a super powerful way to encapsulate some logic in our Postgres database. If we were restricted to only writing SQL statements, these functions would be quite limited. By utilizing database extensions, we can expand this functionality to basically do anything we want! While this example is quite novel, the same method could be used to perform important core responsibilities of your application - such as charging a customer with Stripe, or sending an SMS with Twilio.
