Dear Sergey, I found that Ajin started another thread which migrates replication origins [1].
So how about purging the part from this patch? I.e., commit_ts migrations would be migrated well if both patches are pushed. To keep the behavior consistent, [1] may have to be pushed first. Personally considered, added checks in the patch may look bit ad-hoc, and we should fix from the root cause. [1]: https://commitfest.postgresql.org/patch/6743/
