Thread:Project:Support desk/rev id in revision table is very very loosely packed/reply (3)

I see. The unused revion numbers can have several reasons: Maybe a script like deleteOldRevisions.php has been used in the past, which left these holes. Or you had spam and mass-deleted those entries permanently or or or. However, I don't know of a way to reduce the values of rev_id without loosing referential integrity.
