(please do not top-post it breaks the logic of the thread).
Ah I see I got confused, nodeAgg.c does not track statistics of the
transition or final functions when an aggregate is invoked, and has
never done it. There is no call to pgstat_init_function_usage() when
FunctionCallInvoke() is called so you cannot track statistics
regarding that. Maybe that would be a interesting feature, but
controlled by a different GUC than track_functions.
