Downgrades are generally not supported. You may be able to convince the
older pg_dump to dump the newer database but I don't expect that to
work very well either. The best bet is probably to use the new pg_dump
and manually fix up the dump for 7.3.

This sort of thing is a recipe for desaster for more reasons than this
one. Developing on version X gives no guarantees that deploying on
version Y will work.
Btw., speaking of "v7" and "v8" is about as useful and specific as
talking about Linux 1 and Linux 2.
