During my review and time spent working on the functional dependencies

pg_stats_ext view. I was unsure why the length of the serialised

Perhaps we could improve the view, but I'm not all that sure what
value it would add. Maybe we need to discuss this, but in the
meantime, I've attached a patch which just removes the view completely
Yeah, let's get rid of the view. It was quite useful before introducing
the custom data types (and implicit casts to text), because
pg_statistic_ext would simply return the whole bytea value. But since
then the view kinda lost the purpose and no one really noticed.
