Thanks both -- pushed. I also changed regress/sql/triggers to leave
tables around that have a non-zero tgparentid. This ensures that the
pg_upgrade test sees such objects, as well as findoidjoins.
I refrained from doing the findoidjoins dance itself, though; I got a
large number of false positives that I think are caused by some pg12-era
hacking.
