>, in megabytes.  This is
         the size of each individual file in the WAL log.  It may be useful
         to adjust this size to control the granularity of WAL log shipping.
         The default size is 16 megabytes.
         The value must be a power of 2 between 1 and 64 (megabytes).
         Note that changing this value requires an initdb.
