Hi,

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)

//Bill



Is statistics collection enabled in the config?
