gp_dist_random

Hi,

As per this monitoring recommendations in the Hawq Documentation I'm
running this query but I get only one row back.  All 5 of my segments are
up.

SELECT gp_segment_id, count(*)
FROM gp_dist_random('pg_class')
GROUP BY 1;

Any suggestions?  There's not much documentation about gp_dist_random
function either.
