You're missing the point entirely.  The versioning contract for pg_dump
is that version M.N can dump from servers of versions <= M.N, but the
dump it produces is meant to load into server versions >= M.N.  If you
want a dump that will reload into 8.1, use 8.1's pg_dump.

pg_dump is messy enough already just trying to support this contract.
I have *no* interest in trying to get it to support an --output-version
switch...
