Re: Clustering using dblink

I do not think that using dblink can improve performance. Using dblink will get busy two servers instead of one, not to mention data that are send through network.

You need to specify more information about table (number of rows, indices, query plan),
and then someone might be able to help You.

In some(most) cases VACUUM ANALYZE improves performance.

It's helpfull just for a while. But it's getting
Slow again right now.
And the last one i had is just using dblink for spliting
my schema and table to another server. This's my part
of view's script...;

select * from
dblink('hostaddr=192.168.0.220
port=5432
dbname=d_inventory
user=inventory

'select * from t_stockreal')
as t1(
fc_branch character(6),

But It's more slow. Please somebody help me Please.
