strange error

Hello,

I try to copy a file into a database :
    On our main server (postgresql 8.1 debian etch ia64) no problem.
    On a test laptop (postgresql 8.2 debian testing lenny ia32) I
receive the error :
      the size of the array exceed the maximum allowed (268435455)

db_stats=# COPY table_cat FROM '/var/lib/postgresql/scripts/cat_sql.out'
WITH DELIMITER ';';
ERREUR:  la taille du tableau dépasse le maximum permis (268435455)
db_stats=#

Could you help me ?

Thanks in advance

Guy
