Apart from using the pg_dump from 7.4.6 (see Bruno's answer), you should
take care to use the same locale in the new database cluster. I have had
problems in the past with unique constraints that could not be restored
due to different locale settings. See here:

In my case it was not enough to create the database with a different
encoding, I had to re-initdb the whole cluster :-/
cheers,
