Yes.

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.
