I guess that's one thing rollback segments are good for. In-place modifications of data so order can be maintained.
Yea, in MS SQL, inserts are more expensive with a clustered index because it has to go move junk around on the heap table..
I've just kinda gotten used to the PG approach, as you can always just re-cluster if you do some huge insert of a bunch of data. I guess what I'd be asking for is a feature that would automatically re-cluster whenever new data was committed, however you could just do that with a trigger I suppose..
