Export functions was my original plan, for simplicity, maintenance, etc,
but it seemed like I'd be adding quite a few functions, so the one view
made more sense for an initial version. Also, I knew that pg_dump or some
other stats exporter would have to inline the guts of those functions into
queries for older versions, and adapting a view definition seemed more
straightforward for the reader than function definitions.
