it's not really needed but in some situations you could want to
archive wal segments (for example if you want to shut down the standby
without having to put a really big value in wal_keep_segments) and
while archive_command can be changed at anytime just reloading
archive_mode needs to restart the server. so this is just a good
configuration for 24x7 setups
