OOPS, I just noticed a mistake.

INSERT INTO SP
     SELECT a, b
       FROM ( VALUES ( 'cesp', 'sp' )) AS tmp( a, b )
  LEFT JOIN Sp
         ON (Sp.col1,Sp.col2)=(tmp.a,tmp.b)
      WHERE (Sp.col1,Sp.col2) IS NULL;

I forgot the parentheses that the FROM clause requires when using the VALUES predicate.  Also remember that this only
worksin PostgreSQL versions >= 8.2.
