Jim, > Upsizes? Are you adding more data? If so then yes, analyze would be > good, though autovacuum should handle it for you. I create new Postgres database, upsize a lot of data into it. After that this database goes online and will receive a lot of transactions daily. I'm using PG 8.1 default postgres.conf file. I read than autovacuum may skip some tables which can cause wrong guru hints. So it seems that I should run manually VACUUM ANALYZE for the whole database once for initial statistics colection of those tables, isn't it? Andrus.
