By default, <command>pg_basebackup</command> will wait for all files
to be written safely to disk. This option causes
<command>pg_basebackup</command> to return without waiting, which is
faster, but means that a subsequent operating system crash can leave
the base backup corrupt. Generally, this option is useful for testing
but should not be used when creating a production installation.
