Thanks for sharing this!
> I'm not entirely sure if it's worth a backpatch. This citus feature probably isn't the most critical. So if that's
theonly usecase in the wild that got broken, then that might be fine. But I at least wanted to share that others (i.e.
me)have used this feature.
I found the following description in logical replication docs, which makes me
start thinking that the patch would need to be backpatched.
