  <para>
   Loads a shared object file into the PostgreSQL backend's address
   space.  If the file had been loaded previously, it is first
   unloaded.  This command is primarily useful to unload and reload a
   shared object file if it has been changed.  To make use of the
   shared object, a function needs to be declared using the <xref
   linkend="sql-createfunction"> command.
