DOH! *facepalm* Thanks Tom!

I read docs on set_config() and didn't think to check CREATE FUNCTION.
It does make sense, and now that you point it out, I do remember that
too. I didn't think to check it because this function is *not* secdef,
which is when you'd normally set a search_path on it (a dev
accidentally set it on a non-secdef function).

Thanks, and apologies for the false alarm.
