How about this: We store the first 16 parameters in some fixed array for
fast access like now, and when you have more than 16 then 17 and beyond
get stored in some variable array in pg_proc. This way procedures with
few arguments don't lose any performance but we could support an
"infinite" number of parameters easily. It sounds kind of dumb, but
without some sort of break out of the fixed storage scheme we'll have this
argument forever.
