Just out of curiosity ... how can it possibly be even a little bit sane that fsm_local_map is a single static data structure, without even any indication of which table it is for? If, somehow, there's a rational argument for that design, why is it not explained in freespace.c? The most charitable interpretation of what I see there is that it's fatally undercommented. regards, tom lane
