From  pg_stat_database
-----------------------------
 blks_read,
blks_hit,
_tup_returned,
tup_fetched
 
Reported In pg_stat_user_tables
-------------------------------------

n_live_tup,
n_dead_tup

arvind

pg_stat_user_tables is similar to pg_stat_all_tables, except that it contains only user tables:

oh thanks a lot, we desperately needed to work on the stats collector and since we were using windows platform, there is not even a decent application that reports such information
