db-recovery after update 7.1 -> 7.4 failed

Hi all,

I recently upgraded postgresql from 7.1 to 7.4. I did a

pg_dumpall > backup

then installed the new version and tried to recover my data with

psql template1 <backup

But something went wrong. The log shows the following:

"phpbb_posts_text" and "netjuke_tracks" don't have no rows anymore which
is pretty bad. I had a look at the backup-file, the data is still
there. Do I have any chance to recover the data? Perhaps by
manipulating the backup file?
