noticedthat some tables get stuck in the 's' state during logical replication and they do not move to the 'r' state. I
triedto drop the subscription and create a new subscriber, but the same thing repeated. Also, each time different

This is strange. BTW, we don't save slots after the upgrade, so the
subscriptions in the upgraded node won't be valid. We have some
discussion on this topic in threads [1][2]. So, I think after the
upgrade one needs to anyway re-create the subscriptions. Can you share
your exact steps for the upgrade and what is the state before the
upgrade? Is it possible to share some minimal test case to show the
exact problem you are facing?
