Ah wait, it seems whatever is running the web script is doing some voodoo with
namespaces - the global namespace isn't what it's supposed to be, in which case
not even the aliasing would work properly.

I'm possibly summoning the Daemon Obfuscatis here, but this should work no
matter what:

  [].class.class_eval {
    alias_method(:num_rows, :length)
  }

Feel free to confuse yourself by using module_eval, or define_method.
