    Description

      SELECT TIMESTAMP'2001-01-01 10:20:30' - INTERVAL '10' YEAR AS c1,
      		 
            -INTERVAL '10' YEAR + TIMESTAMP'2001-01-01 10:20:30' AS c2;


      +---------------------+-----------------+
      		 
      | c1                  | c2              |
      		 
      +---------------------+-----------------+
      		 
      | 1991-01-01 10:20:30 | -20110101102030 |
      		 
      +---------------------+-----------------+

      The result for c2 is wrong. It should be the same with c1.

      PostgreSQL returns correct results for the same query:

               c1          |         c2          
      ---------------------+---------------------
      		 
       1991-01-01 10:20:30 | 1991-01-01 10:20:30
