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 use undo 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 saw customers who mistakenly dropped or truncated tables but didn't have any backup. Regards Takayuki Tsunakawa
