The really nasty thing about it is that because the records are now
considered really old, as soon as you do run VACUUM it'll start
removing the rows you want to save...
What you need is a tool to go through and change any transaction ID
significantly in the future and freeze it... You know, like VACUUM...
Oh well..
In 8.1 autovacuum will make this kind of thing obsolete.
Have a nice day.
