I disagree that pg_basebackup should be considered as an authoritative location for covering the material. It would simply link to such a location in notes or “see also”. In short, though, it like pretty much any client program will function correctly regardless of differences with the server. But a physical backup is only truly promised to work if the environment that is processing the data matches the environment that produced the data. David J.
