Pretty strange, isn't it?

It might be worth while dumping one database at a time and see what might
cause the trouble.

Or maybe it is the OS that truncates the file for some odd reason. What is
the platform?

Is you compress the dump on the fly, do you get truncated effect, too?
(pg_dumpall |bzip2 -c >dumpfile)

Hope this helps sorting out your problem.
