But this is not problem even in current patch state. We can restart replica before failover and it works. I tested this
behaviorduring my review.
We can:
- call pg_enable_data_checksums() on master
- wait change data_checksums to inprogress on replica
- restart replica - we can restart replica before promote, right?
- promote this replica
- checksum helper is launched now and working on this promoted cluster
