As already said by others, the "last one win" is somehow a useful feature,
so I'd prefer avoiding erroring out on this one.
This could leave:
(1) improving pgbench doc by spelling out the last one win behavior, but
this is rather standard ;
(2) only warning when this accurs, but that would become noisy for
legitimate uses ;
(3) doing nothing about it.
