The complaint I have about PRAGMA is that it's yet another syntax for
accomplishing pretty much the same thing. If you don't like the GUC
solution, we've already got the "comp_option" syntax for static options
in plpgsql. Sure, that's not too pretty, but that's not a good reason
to invent yet another way to do it.
