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

I need help in understanding the purpose of the following columns produced by PG stats collector in version 9.1
 
From  pg_stat_database
-----------------------------
blks_read,
blks_hit,
_tup_returned,
tup_fetched
Meaning of columns of pg_stat_database:
 
Reported In pg_stat_user_tables
-------------------------------------
idx_tup_fetch,
n_tup_hot_upd,
n_live_tup,
n_dead_tup
pg_stat_user_tables is similar to pg_stat_all_tables, except that it contains only user tables:
