     There will always be at least one WAL segment file, and will normally
!    not be more than (2 + <varname>checkpoint_completion_target</varname>) * <varname>checkpoint_segments</varname> + 1
!    or <varname>checkpoint_segments</> + <xref linkend="guc-wal-keep-segments"> + 1
     files.  Each segment file is normally 16 MB (though this size can be
     altered when building the server).  You can use this to estimate space
     requirements for <acronym>WAL</acronym>.
