Modify schema

Now we have a postgres database running in the cluster, and SchemaHero has created the reservation table. Let's change the table.

Open the reservation.yaml file, and make a couple of changes. Specifically, we want to change the last_name column from varchar(40) to varchar(60). So edit that file, make the change and run kubectl apply on it. Within a few seconds, you should see the new column type reflected in the database.
