Hi Stephen,

We tried pgbackrest as a solution to rebuild the standby cluster, by 
making a differential backup of the primary cluster.

But it seems that pgbackrest is only able to rebuild the standby cluster 
by restoring an existing backup from a repository cluster, and not 
directly from the primary cluster.

We are afraid that creating a backup on the repository cluster is an 
additional step that could be avoided.

Is there some way to rebuild the standby cluster by doing a differential 
backup of the primary cluster directly?
