Perhaps. I got to wonder if this change would not impact code using
their own DestReceiver, resulting in similar leaks when they insert
tuples on-the-fly. Such issues can be surprising for fork an plugin
developers. I was playing a bit with some refactoring of relation
creation for CTAS in the scope of temporary matviews, and noticed this
issue on the CF list, so that was a bit annoying, and issues like that
tend to be easily forgotten..
