I don't recall if it was discussed, but certainly, it was an easier
goal to achieve.
Looks like there are currently 47 warnings with -Wshadow=local. I'm
not quite sure what the definition of "compatible" is for this flag,
but looking at one warning in pgbench.c:4548, I see an int shadowing a
bool. So maybe -Wshadow=local is worthwhile.
