14 - UUID (Universally Unique Identifiers) - PostgreSQL for Beginners
Ave, Coders!
In this lesson, we are going to learn how to add universally unique identifiers.
We are going to achieve this by adding a UUID extension and then inserting a function that will generate UUID (V4) on the fly.
Later we going to use the generated id as a primary key to ensure that it is going to be unique across the whole of our database, regardless of the number of records that it might contain.
