An advantage of not issuing an ERROR if that when working on a list of files (for example a WITH RECURSIVE on the whole data directory?), you can then know which files could not be synced instead of seeing one ERROR about one file, while being unsure about the state of the others. > Could you elaborate why?

Or better idea? We should avoid potentially costly tests in any regression scenario if we have a way to do so. I like your idea of having a pg_mkdir(), that feels more natural to have as there is already pg_file_write(). -- Michael
