I'm not sure if I'd consider it 'sane', but make basically uses the
dependency information, if a job can be run based on its dependency
requirements, then it's started.  For small projects, this isn't
necessairly terrible, but it's not something I would generally
recommend.

I don't see any reasonable implementation, or justification, for
supporting something like that in pg_restore.
