The new pg_basebackup -k option stands for --no-verify-checksums. That
is nearly the opposite of initdb -k, which is for enabling checksums. I
think it could be confusing to have two related tools use the same
option letter for nearly opposite purposes.
How about using capital -K in pg_basebackup? Or maybe it doesn't need a
short option at all.
