Not really since it saves only the first 32 bits of the 64 bit positions it 
will do no worse than a version that supports 32 bits only. It might even 
do slightly better. When this is sorted out, we need to verify that:

- large dump files are restorable

- dump files with 32 bit off_t restore properly on systems with 64 biy off_t

- dump files with 64 bit off_t restore properly on systems with 32 bit off_tAS
LONG AS the offsets are less than 32 bits.

- old dump files restore properly.

- new dump files have a new version number so that old pg_restore will not 
try to restore them.

We probably need to add Read/WriteOffset to pg_backup_archiver.c to read 
the appropriate sized value from a dump file, in the same way that 
Read/WriteInt works now.
