DO I miss something ?

Hi,

Do I miss something?
Shouldn't I have some rows from this query ?

Why is it empty?

SELECT relname, idx_tup_fetch + seq_tup_read as TotalReads from
pg_stat_all_tables
WHERE idx_tup_fetch + seq_tup_read != 0
order by TotalReads desc
LIMIT 10;
relname | totalreads
---------+------------
(0 rows)
