Hi,
We have a table called table1 which contains around 638725448 records.
We created a subset of this table and named it as new_table1 which has
around 120107519 records.
new_table1 is 18% of the the whole table1.
If we fire the below queries we are not finding any drastic performance
gain.
Hi,
Is it possible to put Statement timeout at User Level.

Hi all,
We have upgraded our database server to postgres 8.3.1 on 28th June.
Checked out the performance of Hot on 30th June :
relname n_tup_ins n_tup_upd n_tup_del n_tup_hot_upd
n_live_tup n_dead_tup *table1* *15509156* *2884653* *0* *2442823* *
15509158* *68046*
No, Vacuum Full was not done, but auto_vacuum did click onto table1.
No cluster.

How does it indicate if the entries qualify for hot update ??
hot have a limitation that it do not work if, the index column is updated.
But that not the case over here.

ok.. But we have set fill_factor = 80 for all the indexes on table1.
Is there a way to check if the page is fill and the update is going on a new

We have tried fillfactor for indices and it seems to work.
Need to try fillfactor for table. May for that reason the bulk update
queries don't get the advantage of HOT

Hi List,
Is there anyway so as to indicate the Query Analyser not to use the

From where do the Query Analyser gets the all info to prepare a plan?
Is it only from the pg_statistics table or are there anyother tables
which have this info.
