<para>

This option causes <command>pg_receivewal</command> to not force WAL

data to be flushed to disk. This is faster, but means that a

subsequent operating system crash can leave the WAL segments corrupt.

Generally, this option is useful for testing but should not be used

when doing WAL archiving on a production deployment.
