All,

Hey, is there any good reason why FSM is sized by a static GUC variable?   
Why couldn't we just automatically have the system use as much memory as 
it needs for FSM, provided that it's not more than some reasonable limit, 
like 15% of shared memory?

Seems like that would eliminate one area of user confusion, as well as 
over-allocation.
