Problem migrating from 8.0.3 to 8.2.3

I was following migration document http://www.postgresql.org/docs/8.2/interactive/migration.html and hit the problem I can't solve.

Basically my goal is to migrate data from 8.0.3 to 8.2.3

The error I am getting is:

ERROR:  type "char" is not a domain

Doing:

pg_dumpall -p 5432 | psql -d postgres -p 6543

….

I am thinking that it has something to do with usesysid not being consistent for valid_user type from 8.0.3 to 8.2.3.

On 8.0.3:

labdb=# select * from pg_user where usename='mfgtest';
-[ RECORD 1 ]---------
usename     | mfgtest
usesysid    | 11302
usecreatedb | f
usesuper    | f
usecatupd   | f
passwd      | ********
valuntil    |
useconfig   |

On 8.2.3:

labdb=# select * from pg_user where usename='mfgtest';
-[ RECORD 1 ]---------
usename     | mfgtest
usesysid    | 16612
usecreatedb | f
usesuper    | f
usecatupd   | f
passwd      | ********
valuntil    |
useconfig   |

Any suggesting on how to solve it or where to look or what to try?

Thank you,
