Good - glad to be wrong about that! We do mostly inserts, no updates and very few deletes. We drop entire tables but don't delete often. We have very long rows, though. Do you think the above is a situation likely to create extreme bloat? My Sybase experience with extreme bloat was that it was caused by a three-field clustered index in a very long short-row table over time (~a year). This job doesn't use clustered indexes.
I thought we had to do vacuum full to avoid transaction ID wraparound/reset issues? We do have a lot of transactions, a whole lot.
Are you saying that most admins avoid VACUUM FULL as much as possible? What about XID?
Thanks,
Jennifer
