Hi,
I am experiencing a similar issue as the one mentioned in this post http://stackoverflow.com/questions/3100072/postgresql-slow-on-a-large-table-with-arrays-and-lots-of-updates/3100232#3100232
However the post is written for a 8.3 installation, so I'm wondering if the fillfactor problem is still roughly the same in 9.2, and hence would have a similar effect when adjusted?
Regards Niels Kristian
