Thanks for updating the patch. I confirmed after applying your patch, the ALTER
SUBSCRIPTION could raise an ERROR like:
```
postgres=# ALTER SERVER server OPTIONS (SET port '5434');
ALTER SERVER
postgres=# ALTER SUBSCRIPTION sub REFRESH SEQUENCES ;
ERROR: cannot synchronize sequences if the publisher is running a version earlier than PostgreSQL 19
```
... because the backend always confirms the remove version before updating the local catalog.
I have no comments anymore.
Best regards,
