Can we tweak pg_rewind to take differential backups in PostgreSQL? I was wondering can we hack the pg_rewind code to print the details of the file which have been modified compared to a target server. The list output can then be used for taking differential backups.
Or perhaps we can add an option/switch in pg_rewind --action --action=print ---> would print the files which have changed --action=sync ---> would sync them --action=copy ---> with this option I can specify an additional optino --target-dir where I can copy the files which have changed blocks pg_rewind- https://github.com/vmware/pg_rewind Best Regards, *Sameer Kumar | Database Consultant* *ASHNIK PTE.
