Great proposal, I appreciate it.

Regarding the bloat, check the recent mail threads titled "undo xxx".  A new table storage format is being developed to
useundo logs like Oracle and MySQL instead of generating dead tuples.
 

How about the possibility of adding a feature like Flashback Drop to restore dropped and truncated tables?  I sometimes
sawcustomers who mistakenly dropped or truncated tables but didn't have any backup.
