You're running a 7.something pg_dump against an 8.something server.
This will not work because that pg_dump doesn't know about 8.x
catalog layout.

My advice is never, never, never use the -i option to pg_dump.
It is generally only useful for shooting yourself in the foot,
as is happening here.

You need to reconsider "impossible".  Maybe your search path
isn't what you think it is.
