Postgresql. Generate sets of random integers
Would this be what you want?

SELECT 
   n, generate_series (1,16384), (random()*200000)::int AS id 
FROM  
   generate_series (1,10) AS x(n) ;


or the similar:

SELECT 
    n, i, (random()*200000)::int AS id 
FROM  
    generate_series (1,10) AS x(n) 
  CROSS JOIN
    generate_series (1,16384) AS y(i) ;
