Okay, I tried the following test using the same input file on both
machines. All steps identical.

1) create database test_enc with encoding = 'UNICODE';

2) Create the schema for the 'category' table.

3) \i category_dump.sql

It works on 7.4.3, but I get the duplicate key violation on 7.4.6.

7.4.3 is running on gentoo and was built with emerge postgresql.

7.4.6 is running on Redhat 9 and was built with
./configure --prefix=/var/lib/pgsql --with-python --with-perl

I can probably come up with a clean test case using simplified data.
I'm still hoping someone has the magical solution though...
