I am following the convention that every table's primary key is called 'id', and every table's foreign key is called <referenced-table>_id. This is the convention that I picked up from CakePHP, and probably RoR. This convention was a requirement for the project. So, for example, packages has many files (WHERE packages.id = files.package_id), and files have many lines (WHERE files.id = lines.file_id).
That may be a convention that some newbies with lesser experience follow, but the convention that I and my fellow developers have been following since the 1970s is that wherever possible the same column should have the same name regardless of which table it's on. All the SQL samples you see on any vendor's website still follow this convention, which is why you see "customer.customer_id" and not "customer.id". Note also the use of snake_case and not CamelCaps.
