An 8.3 server certainly ought to accept that command.

What "old 8.3 version" is that? A pre-release snapshot perhaps?
After looking through the commit history, it appears that this setting
was exposed post-beta, which means your results would fit with running
an 8.3 beta or RC release. Leaving aside the wisdom of still being on a
beta release four years later, my advice would be to dump with the
pg_dump that came with the beta release.
