I see. That makes sense. I do have some things that use temporary tables as
well as some jobs that create/drop objects. They are not very frequent nor
are there a huge number objects involved, but I suppose it could still be
an issue. I'm not keen on altering the catalogs, but it sounds like if I
want to be very safe then I would need to.

I previously had old_snapshot_threshold enabled, which would have done this
anyway I believe, including for the catalog tables. That was convenient!

Thank you Laurenz! I've read a bunch of your writing and I've learned a lot
from you. I'm a big fan :-). Thank you for what you do!
