In that case it is a separate issue from Kurt's. Could you follow the
instructions from
https://www.postgresql.org/message-id/1999972.1604957673%40sss.pgh.pa.us
and

providing the output here?

It's unfortunately a nontrivial issue - I have a prototype for a fix,
but it's complicated and not yet complete. And unfortunately I've since

Btw, I'll be more likely to see your reply promptly if you CC me in your
reply.
