Restoring from older pg_dump files

Hello,

I have a data file dumped from a pgsql database version 7.1.2. I am
having troubles restoring this data to a new database server version
8.1.5. Are there some gotcha's involved, did the format change, or some
such?

I have used the createdb command to make the basic database. it's when
I use the \i option in psql that I see invalid commands, syntax errors,
invalid roles, etc.

The original file was created with pg_dump -cou.
