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:

http://www.postgresql.org/docs/9.2/static/monitoring-stats.html#PG-STAT-DATABASE-VIEW
 

 
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:
