The general philosophy is to copy everything except what we know for
sure can be excluded. In practice, this means sticking to what
pg_basebackup excludes because that list is vetted by the community.
Also, relocating the log directory is easy using the log_directory
setting, so that's what I recommend if it's an issue. Some users do
want to backup their logs.
