Pgbench *currently* already accept multiple "-f ..." options, and this is 
a good thing to test realistic loads which may intermix several kind of 
transactions, say a lot of readonly and some update or insert, and very 
rare deletes...

Now if you do not need it you do not use it, and all is fine. Once you 
have several scripts, being able to "weight" them becomes useful for 
realism.

Ok, I understand this "afterward modification" objection.

What if the -w would be required *before*, and supply a weight for (the 
first/maybe all) script(s) specified *afterwards*, so it does not modify 
something already provided? I think it would be more intuitive, or at 
least less surprising.

Maybe -f file.sql:weight (yuk from my point of view, but it can be 
done easily).
