Server which receives and lists payments

I made this project as an interview assignment. I used https://github.com/kyleconroy/sqlc to generate /postgres folder from sqlc.yaml.

The one thing I would do differently if this project would be deployed in production and used by customers, is not using float64 (in Go) and float(in postgres) for money type. I should have used numeric in postgres. However, since Golang does not have an equivalent for big numbers (such as numeric) it stores these values as strings. Therefore I decided I do not want to implement basic integer operations (such as +, -, *, /) on strings. As this project will not be deployed and used anywhere, I decided to use float64 and float for money type.

To stop the container

To run the app in development mode
