Change subject: Don't do UNDO garbage collection until after the REDO->UNDO transformation ...................................................................... Don't do UNDO garbage collection until after the REDO->UNDO transformation Reasoning about what has been garbage collected and not while at the same time generating UNDOs is tricky. Particularly taking REINSERTS into account and multiple row versions merging (part of a follow up patch). This moves UNDO garbage collection to after the transformation and simplifies things a bit, at the cost of some extra work.
