-    Write-Ahead Logging (WAL) puts a checkpoint in the transaction log
-    every so often. (To adjust the automatic checkpoint interval, see
-    the run-time configuration options <xref linkend="guc-checkpoint-segments">
-    and <xref linkend="guc-checkpoint-timeout">.)  The
-    <command>CHECKPOINT</command> command forces an immediate
-    checkpoint when the command is issued, without waiting for a
-    scheduled checkpoint.

     A checkpoint is a point in the transaction log sequence at which
     all data files have been updated to reflect the information in the
     log.  All data files will be flushed to disk.  Refer to
!    <xref linkend="wal"> for more information about the WAL system.
