[REPOST] Problem for dumping a 6.5.2 database

Hello,

I'm trying to dump a PostgreSQL 6.5.2. database table in order to add it
in a PostgreSQL 7.3.3 database but I'm encountering some errors :

When I try to do the dump, I get :

[bouchon@old_db]$ pg_dump -x -v -u -t tablename -D -f tablename_dump.sql
thedatabasename
Username:
Password:

-- last builtin oid is 17120
-- reading user-defined types
-- reading user-defined functions
getFuncs(): SELECT failed. Explanation from backend: 'pqReadData() --
backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
'.

If I connect to this database via psql and I make a \d tablename I get :

[bouchon@old_db]$ psql -u thedatabasename
Username:
Password:

Welcome to the POSTGRESQL interactive sql monitor:
Please read the file COPYRIGHT for copyright terms of POSTGRESQL

type \? for help on slash commands
type \q to quit
type \g or terminate with semicolon to execute query
You are currently connected to the database: thedatabasename

thedatabasename=> \d tablename;
pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request. thedatabasename=>

But I can do select * from thetablename where pk_id=10 even select *
from tablename without any problems.

I don't understand why the pg_dump is not working... :-(

Can you help me ?

Thanks in advance !
