*** 1691,1702 ****
           Sets a minimum statement execution time (in milliseconds)
           above which a statement will be logged.  All SQL statements
           that run longer than the time specified will be logged together
!          with their actual duration.  Setting this to zero (the default)
! 	 disables time-based logging.  For example, if you set it
           to <literal>250</literal> then all SQL statements that run longer
!          than 250ms will be logged.  Enabling this
!          option can be useful in tracking down unoptimized queries in
!          your applications.
           Only superusers can increase this or set it to zero if this option
           is set to non-zero by the administrator.
