In thinking about this I'm wondering if I'm making this harder then it
needs to be. If I could write a function that builds, and returns the
RSS file that would accomplish what I want - assuming that I could call
the function from a webpage. Can Postgres functions be called from a
URL, similar to how PL/SQL files can be in Oracle?
