Missing system views?

I am trying to check performance in out database but I seem to be
missing something. I try to run :

select relname, idx_tup_fetch + seq_tup_read as total from
pg_stat_all_tables

but all the tables have total = 0, shouldn't these be numbers > 0?

And shouldn't there be views like pg_statio and pg_stat? (they do not
exist in my database...)


Regards,

BTJ
