Problems recovering sequences from a backup done with pg_dump

Hi all,

    I've done a dump from a PostgreSQL 7.4.5 using pg_dump and it worked find. The problem comes when I restore the backup and all the sequences values are 1. I can fix the problem manually giving the sequeces their appropiate value but I wonder wether is a way to force pg_dump to store this information. Any help will be welcome!

            Thanks in advance,
