Guys,

I need some help to decide when i should reindex the indexes in the table.
Postgresql 7.4.5 and linux O.S.
Below is the results of vacuum analyze verbose on the table

INFO:  vacuuming "public.rpt_metrics"
INFO:  index "rpt_metrics_date_network_advertiser" now contains
102960776 row versions in 717963 pages
DETAIL:  198809 index pages have been deleted, 20000 are currently reusable.
CPU 30.95s/3.51u sec elapsed 770.69 sec.
INFO:  index "rpt_metrics_date_network" now contains 102960776 row

There were 56377053 unused item pointers.
0 pages are entirely empty.

INFO:  analyzing "public.rpt_metrics"
INFO:  "rpt_metrics": 2920718 pages, 3000 rows sampled, 176302
estimated total rows
VACUUM

When should i ideally reindex this table ?.
(once in a month, weekly....etc)
