%% For @global stats it's simple, we can get all of them with a simple query

%% to know which stats should be rates and which stats should be plain. This
%% leads to the fact that when we need to get all of them we have to know
%% the real list of stats being requested. It can be achieved by various
%% means. I chose to just hardcode it (should be fine as it's for backward
%% compat only).
