Invalid byte sequence

I am getting the following error when trying to migrate a db from
8.4.0/FreeBSD 7.1 to 9.0.1/FreeBSD 8.1, both are VMware virtual machines
with FreeBSD amd64...

> data1# psql -U pgsql template1 < /data/maia.sql
> <snip>
> template1 < /data/incoming.sql
> ERROR: invalid byte sequence for encoding "UTF8": 0xe93532
> CONTEXT: COPY awl, line 7884

I checked the build options for both pgsql port installations and found
only difference being WITH_INTDATE=true in the destination server. I
checked the line in the source file created by pg_restore and see no
date involved in the record...

pg_restore -l on the source file dump file...

; Format: CUSTOM
; Integer: 4 bytes
; Offset: 8 bytes
; Dumped from database version: 8.4.0
; Dumped by pg_dump version: 8.4.0

Is it the WITH_INTDATE option and I should rebuild or something else
causing this error?
