Andre,
I noticed that enable_bitmapscan and enable_seqscan are off, is there a reason for it? Have you tried with enable_bitmapscan on?
How much RAM do you have? What kind of disks are being used?
Beste regards,
Reimer

Hello,
A friend asked for help to accelerate some postgresql queries on postgresql
8.1.2 for windows.
He is comparing with firebird.
Firebird was being up to 90 times faster at some queries.
Attached is a gziped text file containing some steps I tried on a simple
example query.
Could get improvements from 270 seconds to 74 seconds.
But Firebird effortless ly still can perform the same query at 20 seconds.
Please, do you have some suggestion?
Thanks.
Andre Felipe Machado
