I think he can get what he wants by doing a SQL dump instead of an ordinary dump.

For instance, from PG Admin III, right click on the database cylinder and choose the plain text options. You'll be left with a command something like this:

pg_dump --host localhost --port 5433 --username postgres --format plain --create --clean --inserts --column-inserts --verbose --file "q:\donzbrane.sql" "Chess"

(Here, I am sending the output of a database called 'Chess' to a SQL file called donzbrane.sql).
By examining the options and command line choices for pg_dump from the manuals, you can also create exactly what you want.
