PostgreSQL: 8.2.4
I did the following query on my database:
select * from pg_stat_all_indexes;
My hope was to see if my indexes are being used. The values I got were
all 0's for the columns: idx_scan, idx_tup_read, and idx_tup_fetch.
Is there a different query to tell me how often indexes are being used?
My postgresql.conf file settings are:
#-----------------------------------------------------------------------
----
# RUNTIME STATISTICS
#-----------------------------------------------------------------------
----
# - Query/Index Statistics Collector -
#stats_command_string = on
#update_process_title = on
#stats_start_collector = on # needed for block or row stats
# (change requires restart)
#stats_block_level = off
#stats_row_level = off
#stats_reset_on_server_start = off # (change requires restart)
# - Statistics Monitoring -
#log_parser_stats = off
#log_planner_stats = off
#log_executor_stats = off
#log_statement_stats = off
