Isn't it better if we use option 2) at all places as then we won't
need any special check inside ReorderBufferChangeMemoryUpdate()?
> Yet another option could be to create a new API say ReorderBufferReplaceChangeMemoryUpdate(), which takes, 2
parameters,oldchange, and newchange as inputs, it will compute the difference and add/subtract that size. Logically,
thatis what we are actually trying to do right? i.e. replacing old change with the new change.

Note that in ReorderBufferToastReplace(), the new tuple is replaced in
change so by the time we want to do this computation oldchange won't
be preserved.
