Hi

We are using openshift environment and postgres version 15.2. We want to change storage from ceph to local storage. So, Storage team made default storage as local. Now, I created a new cluster with same postgres version and I am planning to take backup from old cluster to new cluster. Size is 100gb. Ram 24gb, cpu 2.

My question is, is there a combination of pg_dump and pg_restore that takes less time to complete the task?

Last time it took more than 8hours. We were taking schema only dump using dumpall . Then data only backup using pg_dump in directory format.
