pg_dump on 7.4

Hi,

We have a running postgresql 7.4 on our server (SuSE Linux 9), and at the moment there is no chance to upgrade. Through an unusual combination of constraints (spanning over schemas) the dump cannot be imported without errors anymore. 

Are there any statically compiled 8.x binaries (with which it works) available which I could use to backup the database?

Thanks
Jürgen
