Hello

I want to see statistics about the use of my postgresql 8.3 in Ubuntu 8.04.1
(Hardy) Server.

In my postgresql.conf I have the follow configuration related to statistics:

"""
#---------------------------------------------------------------------------
---
# RUNTIME STATISTICS
#---------------------------------------------------------------------------
---

# - Query/Index Statistics Collector -

#track_activities = on
#track_counts = on
#update_process_title = on


# - Statistics Monitoring -

log_parser_stats = on
#log_planner_stats = off
#log_executor_stats = off
#log_statement_stats = off
""""

But when I execute this command "select * from pg_stat_all_tables;" I get
all the rows with the values (except the 3 first values) set to 0:

"""

| seq_tup_read | idx_scan | idx_tup_fetch | n_tup_ins | n_tup_upd |
n_tup_del | n_tup_hot_upd | n_live_tup | n_dead_tup | last_vacuum |

"""

What I need to do to obtain the values updated in pg_stat_all_tables? Or the
statistic are stored in other place?

Any help will be appreciated.
Thanks in advanced.
