Isn't this a non-problem? This behavior is in line with the
documentation, so I would suspected that if directory name is
specified as "-" in plain mode, it should create the folder with this
name.
Do you consider having a folder of this name an annoyance?

This would change the spec of pg_basebackup, so no? Does the current
behavior have potential security issues?
