There was a problem hiding this comment.
Actually we have the main scenario to test this feature.
First
- Run HA cluster - 1 master and 1 replica.
- Run pgbench to fill cluster.
- After that block streaming WAL to replica by iptables(firstly check taht it's possible)
- Run pgbench again, after that master will have more data than replica
- Catchup-push from master PGDATA and from replica LSN.
- Replica catchup-fetch this incremental-backup
- Compare that master and replica has the same data.
P.S. It would be better to create several incremental backups which catchup-fetch will apply
