Agreed. I spent close to a week trying different benchmarks and configurations and simple test cases on a test server and my laptop, and couldn't demonstrate bgwriter making a positive impact in any configuration I tried. The theory behind the patch is sound, but it looks like a lot more testing and analysis is needed. > o Error correction for n_dead_tuples > > This shows as waiting on another patch. Again, I am thinking to > keep it for 8.4. It was waiting on the "vacuum oldestxmin" patch, which didn't make it to 8.3. I don't care for the patch myself, but it was submitted well before feature freeze and deserves a review. It looks good to me at first glance. -- Heikki Linnakangas EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
