Do we want to mention in the docs that the same decision-making is
done for *all* files with matching names, aka the fact that if a file
is listed and found in a sub-folder it is skipped? postmaster.opts or
similar friends are unlikely to be found in anything but the root of
the data folder, still the upthread argument of documenting precisely
what basebackup.c does sounded rather convincing to me.
