[Autovacuum] Issue to understand some logs

Hi everybody,

I have trouble understanding some logs of postgreSQL.

Here you can find a log from the auto-vacuum process :

2012-12-17 16:38:58 CET LOG:  automatic vacuum of table "flows.public.agg_t344_outgoing_a41_src_net_and_dst_net_f5":
indexscans: 0 
    pages: 0 removed, 59820 remain
    tuples: 0 removed, 5801752 remain
    system usage: CPU 0.93s/0.95u sec elapsed 423.07 sec

I am right to conclude that there is 5801752 available tuples in the previous table ?

If true, I am very confused because our table can not exceed 2592000 tuples (We delete old ones).

To be sure I tried to run the following query to count availables tuples :

select count(*) from agg_t344_outgoing_a41_src_net_and_dst_net_f5;
  count
---------
 2584398
(1 row)

Can someone give me a clue ?

Best regards,

Baptiste.
