hi guys,
yesterday we upgraded 8.x to 9.x
in one table we have nearly 50 million records which are, every night, crunched by an insanely complex stored procedure written in plpgsql
this takes normally 3 to 3 1/2 hours
after the upgrade it took only 2 hours
do you think this is because 9.x performs better or is it possible that our 8.x installation has been muddled up somehow? (we did totally clean install/upgrade with drop/import)
