Thanks! I do prefer the macros definition ordering that you're proposing (that makes pgstatfuncs.c "easier" to read).

As far the names, I think it's better to replace "TAB" with "REL" (like in v4 attached): the reason is that those
macroswill be used in [1] for both tables and indexes stats (and so we'd have to replace "TAB" with "REL" in [1]).
 
Having "REL" already in place reduces the changes that will be needed in [1].
