Hi, I wanted to hop in here on one particular issue:

Right now, the lack of sequence replication is a rather large foot-gun on logical replication upgrades. Copying the sequences over during the cutover period is doable, of course, but: (a) There's no out-of-the-box tooling that does it, so everyone has to write some scripts just for that one function. (b) It's one more thing that extends the cutover window. I don't think it is a good idea to make it mandatory: for example, there's a strong use case for replicating a table but not a sequence associated with it. But it's definitely a missing feature in logical replication.
