Hi, I am running a 9.1 server at Ubuntu. When I upgraded to the current version
I did a pg_dump followed by pg_restore and found that the db was much faster.

compare the two (actually identical) databases. This is
Interesting.
Thanks for the work-around.
Regards,
Nick

That worked like a charm! Many thanks. But how comes, the queries are also fast
after a restore

Are you running a lot of full table updates?

Hi all,
We have put some deferred constraints (some initially immediate, some
initially deferred) into our database for testing with our applications.
I haven't seen any noticeable loss in performance, but I am not sure I can
properly simulate our full production environment load levels in my
