Subject: [GENERAL] update queries taking lot of time
Hi,
I am running update query of the form "update tablename set x = y where
exists (select .....)"
These queries are taking lots of time. I dropped all indices on the
table
which provided some improvement but not remarkable performance. I am
looking
for ways to improve it. Can someone suggest what all can be done to
improve
it. These queries are being executed from within a pl/pgsql function.
Regards,
Vinita Bansal
