>   The default value is defined as the value that the parameter would
   have had, if no <TT
CLASS="COMMAND"
>SET</TT
> had ever been issued for it in the
   current session.  The actual source of this value might be a
   compiled-in default, the configuration file, command-line options,
   or per-database or per-user default settings.  This is subtly different
   from defining it as <SPAN
CLASS="QUOTE"
>"the value that the parameter had at session
   start"</SPAN
>, because if the value came from the configuration file, it
   will be reset to whatever is specified by the configuration file now.
   See <A

>   The transactional behavior of <TT

   <TT
