Defragment for a dbspace

Add at the 'DEFRAGMENT' SQL Api , the option to defragment an entire dbspace. 


We have set in our environment tables and partitions with historical data, so, they are tables or partitions who have any changes (include/excluded data). 

Most of them are set in the same dbspace and from time in time, we remove the oldest, opening a few gaps of free space over the firsts chunks of the dbspace. These dbspace are made of few chunks and we want to move all data to the firsts and remove the last chunks to recover disk space.

Why is it useful?
Who would benefit from this IDEA? The business of the company , because will reduce the maintenance stop time.
How should it work?

The command shouldn't care about the number of fragments of the tables, they only should move all fragments together, where should be only an I/O work.


For certain situations will allow reducing space utilization. Mainly after certain maintenance like compressing tables, data movement, and purge of data.


Today, as far I know, there is no plausive or usable workaround  unless export/move all data to another place and then back with it.
