   ON  <event>  RESTRICT  triggers  are  now  executed after the   statement allways, ignoring any explicitly set
deferredmode.
 
   This  is  pretty close to Date's SQL3 interpretation, or IMHO   better. Date says that they are checked BEFORE each
ROW, but   that  would  ignore  the SET character of a statement. Now we   have  correct  semantics  for  all  4
possible  referential   actions.
