In some of the intermediate version of the logical-decoding, we had
collected in form of changes and later we changed it so that we can
execute all the invalidation on abort. I just browsed old patch and
fetch the changes to collect the invalidation in form of changes. I
have rebased on the current head so that we collect both in form of
changes as well as collection of the invalidation. So if we get
individiaual invalidation we execute them and on abort we execute all
the invalidation together.
