PostgreSQL 8.1.0 RHEL / Debian incompatible packages

I just tried to move my database files over from a CentOS 4.2 (RHEL AS 4
clone) machine to Debian 3.1. Unfortunately, the server complains:

2005-12-07 11:55:04 CET FATAL: database files are incompatible with server
2005-12-07 11:55:04 CET DETAIL: The database cluster was initialized
without HAVE_INT64_TIMESTAMP but the server was compiled with
HAVE_INT64_TIMESTAMP.
2005-12-07 11:55:04 CET HINT: It looks like you need to recompile or
initdb.

The message is clear enough, but I'm kinda disappointed because I am
using the official packages for both distribution:

RHEL 4:
postgresql-server-8.1.0-2PGDG.i686.rpm from
http://www.postgresql.org/ftp/binary/v8.1.0/linux/rpms/redhat/rhel-as-4/

Debian:
postgresql-8.1_8.1.0-3_i386.deb from
http://packages.debian.org/testing/misc/postgresql-8.1

It's too bad these two binary distributions are not compatible with
respect to the database files.

Is there a good reason that the official RPM on postgresql.org is not
build with HAVE_INT64_TIMESTAMP ? It would have been so nice if this
would have worked. :-/

Sincerely,
