Hi,
I have a Primary and Standby running on Postgres v11.7.
I was following the document to upgrade a PG v11.7 cluster to PG v13.4.
After upgrade using pg_upgrade on primary, I ran rsync to setup standby
PG13 but when I started the primary, the replication slots were not
present. How will standby start streaming in this case?
We are using physical replication slots.
Thanks,
Nikhil
