Tom: I don't "figure" it, it's just all I could get from documentation and discussion that is rather sparse in concrete examples. For example, this thread includes two postings that indicate that session variables can be done, and make references to commands, but fail to actually show how to do them. The documentation is the same way. The one example for FOR loops is confusing and overly broad. It fail to step through the example code clearly showing where a value from a temp table is extracted and stored in a variable. I certainly don't mean to be critical, because PostGres is a fantastic product. However, we in the open source community need to learn that software is only as good as its documentation. Concrete examples are the heart of good technical documentation. I would go so far to say that any technical documentation w/o simple concrete examples demonstrating each point is at best a quarter as useful as it might be. I guess I should live by my own words, so for concrete examples of concrete examples, please see any of the pages in the Idocs Guide to HTML.
