7.1 -> 7.3 migration timestamp problem

System Configuration
---------------------
  Architecture (example: Intel Pentium)     : pIII

  Operating System (example: Linux 2.0.26 ELF)  : OpenBSD 3.2

  PostgreSQL version (example: PostgreSQL-7.3.2):   PostgreSQL-7.3.2

  Compiler used (example:  gcc 2.95.2)      : 2.95.3


Please enter a FULL description of your problem:
------------------------------------------------
Migrated from 7.1.3 to 7.3.2 by running 7.3.2's pg_dumpall on existing=20
databases, running initdb on a new data directory, starting up the new data=
=20
with the new pg binary, and running the addepends script in the contrib=20
directory.

Everything works, except inserting or updating on tables with timestamps.
Trying to do so from psql produces this:

redes=3D# update admin set email=3D'flake' where admin_id =3D 1;
FATAL:  Pre-7.3 object file made an elog() call.  Recompile.
server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Succeeded.

The table for this example looks like this:

redes=3D# \d admin
                                         Table "public.admin"
   Column    |           Type           |                          Modifier=
s=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=
=20=20
-------------+--------------------------+----------------------------------=
---------------------------
 admin_id    | integer                  | not null default=20
nextval('public.admin_admin_id_seq'::text)
 email       | text                     | not null
 password    | text                     | not null
 first_name  | text                     |=20
 last_name   | text                     |=20
 create_date | timestamp with time zone |=20
 update_date | timestamp with time zone |=20
Indexes: admin_pkey primary key btree (admin_id),
         admin_email_key unique btree (email)
Triggers: admin_create_tr,
          admin_update_tr


If I create a new table with a timestamp column, everything works just fine=
