Hi Tom,
Thanks for the quick reply.
I expanded the tests by creating AWS RDS PostgreSQL databases from scratch for versions 14.6, 14.7, 15.2 and running
thementioned statements.
It's working in 14.6 but fails in both 14.7 and 15.2 with the mentioned issue.
I've also tried 14.7 locally and it's working fine here too so I guess you can safely ignore this bug and I'll be
raisingan issue with AWS support.
Regards,
João

It still works like that for me in 14.latest. Perhaps you installed an
event trigger that is doing something incautious?
