Thanks, > How large is $PGDATA/global/pgstat.stat ?

Does it mean that CPU usage rate of stats collector process could possiblly reach 100% unless the postgres is updated to the version 8.4.x, instead of 8.3.x? (So far I'm planning to update the postgres to the version 8.3.9) Regards, 【節約!】インターネット代、見直しませんか? 月額1,480円で快適ブロードバンド |
