[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(at)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(at)old_db]$ psql -u thedatabasename
Username:
Password:

Welcome to the POSTGRESQL interactive sql monitor:

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 !
