Bug reference:      18147
Logged by:          Hans Buschmann
Email address:      buschmann@nidsa.net
PostgreSQL version: 16.0
Operating system:   Fedora 38 x86-64 64bit, also on Win64
Description:        

We have recently moved our production cluster from pg15.4 to pg16.0

In a long lasting correct case (since about pg 9.6) an update statement now
fails with $subject.

I have simplified the case and the error remains (here shown on windows)

FEHLER:  invalid perminfoindex 0 in RTE with relid 17034

I have found a relating discussion under

https://www.postgresql.org/message-id/flat/CANQ0oxfxBKKTReQgSh_KbL99DqdjfBZTastC0XT2ZZMBkAhTQw%40mai...

but could not resolve the problem.

The query is quite simplified.. Perhaps it is good to now, that the table
or_followup has an inherited table or_followup_archiv (= relid 17034) which
is chosen by of_season and has not the same index definitions as
or_followup.

Thank you for looking!
