Thread: pgsql: Make pg_rewind skip files and directories that are removeddurin
Make pg_rewind skip files and directories that are removed during server start. The target cluster that was rewound needs to perform recovery from the checkpoint created at failover, which leads it to remove or recreate some files and directories that may have been copied from the source cluster. So pg_rewind can skip synchronizing such files and directories, and which reduces the amount of data transferred during a rewind without changing the usefulness of the operation.
