This is a feature request, but I need it too.

My work-around is to use a DO statement that iterates over pg_constraint 
to duplicate all interesting constraints giving each a new name and ends 
with a RAISE EXCEPTION 'OK'. If the execution ends with that "error", 
all constraints are valid. I guess you could wrap it into a BEGIN ... 
ROLLBACK to get the same effect.
