Yep. I have been procrastinating on swapping all this back into my
brain. I'll start working on it today. I think I just take the
reverted test and make the UPDATE a DELETE, set mwm 64 kB, make the
table have 9000 rows and maybe consider using your:

delete from test where ctid::text like '%,2__)';

But, unfortunately, to be able to commit it, I'll have to remember
everything about this. I'll begin now...
