Exploring Vertica's INTERPOLATE predicate

Vertica has a special feature to join tables and fill in the last available values where values would otherwise be null. I had a similar use case and wanted to test how I could make the best use of it. I played with simple examples and got it right, but with a slightly more complex one, I was stuck or maybe I just couldn't understand what was happening. So I posted a question at Stackoverflow
