I it seems that slowness is caused by grouping by columnexchrate numeric(13,8)
exchrate has different values in few rows. It has usually value 0 In this sample query it is always 0.I tried not change exchrate with nullif( bilkaib.EXCHRATE,0)
but this does not up speed query, no idea why. Andrus. -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
