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": index scans: 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.
