Finally, we have reached the end of our tutorial. We presented in it how to connect to PostgreSQL from the Go language using three different approaches, how to perform CRUD operations and how to create a well-structured data access layer using clean code practices and the Repository design pattern.

It was just an introduction to give a general overview of what an application’s integration with the PostgreSQL database should look like. However, with these basics, you can create much more advanced projects being sure that they are robust to any future changes.

Good luck!
