Description
   RESET restores run-time parameters to their
   default values. Refer to
   SET
   for details. RESET is an alternate spelling for
   
SET variable TO DEFAULT
   
   The default value is defined as the value that the variable would
   have had, had no SET ever been issued for it in the
   current session.  The actual source of this value might be a
   compiled-in default, the postmaster's configuration file or command-line
   switches, or per-database or per-user default settings.  See the
   Administrator's Guide for details.
  
   See the SET manual page for details on the transaction
   behavior of RESET.
