Also be aware that you won't get a synchronized snapshot and therefore
the resulting dump might not be valid..
Looking at pg_dump, for my 2c anyway, it'd be nicer if we threw an error
on parallel dump request when the major version doesn't support
synchronized snapshots, unless the user explicitly passed
--no-synchronized-snapshots, indicating that they don't care.
