I think he'll have trouble even with that :-( ... 7.3 pg_dump will try
to use column-name-list syntax in its COPY commands, which the 7.2
server won't like.

AFAICS the only answer is to run the data dump through a filter (sed or
perl or whatever) to edit the COPY commands to a format 7.2 will take.
