Description

After running db and view compaction on a 70K doc db with 6+ mio. changes - it takes up 0.8 GB. If copying the same documents to a new db (get and bulk insert) - the same date with 70K changes (only the inserts) takes up 40 mb. That is a huge difference. Has been verified on 2 db's that the difference is more than 65 times the size of data.

A "Compact and copy" feature that copies only documents, and resets the changes for at db would be very nice to try and limit the disk usage a little bit. (Our current test environment takes up nearly 100 GB... )

I've attached the dump load php script for your convenience.
