I've experienced a similar problem with a data-only dump using 8.0.1's
pg_dump.  It seems that the COPYs (or INSERTs) are generated in
alphabetical order of table name, ignoring foreign key contraints and
requiring the output to be post-processed.  In a full dump of the database
the constraints are added after the data is inserted so there are no
problems.  See the two attached dumps of the same database as an example.

I am running under HP-UX 11.11 on PA-RISC 2.0, (both 32- and 64-bit builds
tried) built using the native ANSI C compiler.  All tests passed when
running 'make check'.
