-----------
When doing a parallel restore, we must guard against out-of-range dependency
dump IDs, because the array we're using is sized according to the highest
dump ID actually defined in the archive file. In a partial dump there could
be references to higher dump IDs that weren't dumped. Treat these the same
as references to in-range IDs that weren't dumped. (The whole thing is a
bit scary because the missing objects might have been part of dependency
chains, which we won't know about. Not much we can do though --- throwing
an error is probably overreaction.)
Also, reject parallel restore with pre-1.8 archive version (made by pre-8.0
pg_dump). In these old versions the dependency entries are OIDs, not dump
IDs, and we don't have enough information to interpret them.
Per bug #5288 from Jon Erdman.
