Locality of access decreases, of course, and depending on your data size, you hit something like to 2 or 4 additional disk seeks per partition for index-based accesses.

Sorry, I haven't got much experience with autovacuum, since most of other databases are INSERT-only (or get VACUUMed automatically after major updates). -- Florian Weimer <fweimer@xxxxxx> BFK edv-consulting GmbH http://www.bfk.de/ Kriegsstraße 100 tel: +49-721-96201-1 D-76133 Karlsruhe fax: +49-721-96201-99
