OS is Debian 3.1 Sarge with PostgreSQL 7.4.7 (7.4.7-6sarge1) > with the libpq frontend library. Note that 7.4.7 is not the current bugfix version of 7.4.x. It is 5 or 6 patches behind. > So I'm asking me if it is useful to update to the actual 8.2 version and > if we could experience performance improvement only by updating. 8.2 will give you a number of features which should greatly improve your performance situation: 1) partitioning: break up your main data table into smaller easier-to-maintain segments (this will require some application changes) 2) VACUUM delay, which lowers the impact of vacuum on concurrent queries 3) AUTOVACUUM, which helps keep your tables in reasonable maintenance. -- --Josh Josh Berkus PostgreSQL @ Sun San Francisco ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
