Fedora Core 3 x86_64 compat libraries?

I have an AMD64 Fedora Core 3 server with Postgresql 8.0.1 that I want
to upgrade to the latest version. Since 8.0.2 incremented the libpq
version I can't install the official RPM packages. I found a
message[1] to this list which had a compat-postgresql-libs[2] RPM, but
that's an i686 package. Where can I find a x86_64 version or source
for this package? Is that package compatible with 8.0.4?
