# Copyright (c) 2021-2025, PostgreSQL Global Development Group # # This test aims to validate that pg_combinebackup works in the degenerate # case where it is invoked on a single full backup and that it can produce # a new, valid manifest when it does. Secondarily, it checks that # pg_combinebackup does not produce a manifest when run with --no-manifest.
