These are to be expected if you try to restore a dump made with an old
version of pg_dumpall. If you don't see any other problems, just ignore
'em.

BTW, it's usually best to try to make the dump with the newer version of
pg_dump/pg_dumpall. This can be a pain in the neck though if you are
using a packaging system that wants to update all the PG executables at
the same time :-(
