The fact that this allows you to create essentially derived values from groups of re-used columns is itself remarkable and can be used to implement path traversal etc. which is not directly supported in PostgreSQL in the sense that it is in Oracle or DB2.
What exactly do you mean with "path traversal" here? If you are talking about Oracle's CONNECT BY then this is fully supported in PostgreSQL using a recursive common table expression.
