What would you want the checkpointer's ps to say ?

Normally it just says:
postgres 3468 3151 0 Aug27 ? 00:20:57 postgres: checkpointer

Or do you mean do the same thing as now, but one layer lower, like:

@@ -8728,6 +8725,9 @@ CreateCheckPoint(int flags)
+ if (flags & CHECKPOINT_END_OF_RECOVERY)
+ set_ps_display("recovery checkpoint");
