We had a similar report back in April:

https://www.postgresql.org/message-id/flat/152337570402.31228.237601111670899842%40wrigleys.postgresql.org

but that didn't have enough information to debug the problem, and
neither does this.  Can you provide a *self contained* test case,
or failing that, do some debugging of your own as suggested in the
previous thread?
