        id int(20) NOT NULL,
      		 
        name varchar(16) NOT NULL default ''
      		 
      );
      		 
       
      		 
      INSERT INTO t1 VALUES
      		 
        (3,'xxx'), (7,'yyy'), (4,'xxx'), (1,'zzz'), (5,'yyy');
      		 
       
      		 
      select sum(id) filter (where name = 'yyy') from t1; -- should return 12
