Allow streaming the changes after speculative aborts.
Until now, we didn't allow to stream the changes in logical replicationtill we receive speculative confirm or the next DML change record afterspeculative inserts. The reason was that we never use to processspeculative aborts but after commit4daa140 it is possible to processthem so we can allow streaming once we receive speculative abort afterspeculative insertion.We decided to backpatch to 14 where the feature for streaming in progresstransactions have been introduced as this is a minor change and makes thatfunctionality better.Author: Amit KapilaReviewed-By: Dilip KumarBackpatch-through: 14Discussion:https://postgr.es/m/CAA4eK1KdqmTCtrBR6oFfGELrLLbDLDedL6zACcsUOQuTJBj1vw@mail.gmail.com
