Hello, The db in the application I maintain but didn't write (it obviously makes use of PG, v 8.3), has been systematically growing in size from about 600M to 1.6G. At the same time, the performance of the app has degraded significantly (several times). So I've done VACUUM ANALYZE on entire db. Nothing. The db did not decrease in size, the performance stayed the same. So I backed it up using pg_dump, deleted database, and recreated it from backup. The size of db on disk went down to 600M, performance recovered to the original level. Why that is so? I thought that VACUUM ANALYZE does everything that is needed to optimize disk usage?
