pg_restore error

hello everybody,

i am pascal, i am from paris, france, and i am a newbie here.
well, i have a problem with the pg_restore command and i don't find 
any informations on the web about it. when trying to restaure a 
database, i have the above error :

[postgres@preprod2 pgsql]$ bin/pg_restore -d interlig -Fc 
/home/postgres/dump_20021010new.out
pg_restore: [archiver (db)] could not execute query: ERROR:  Relation 
'cable_id_cable_seq' already exists

and i try this :

[postgres@preprod2 pgsql]$ bin/pg_restore -d interlig -Fc 
/home/postgres/dump_20021010new.out -t synd_article
pg_restore: NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit 
index 'synd_article_pkey' for table 'synd_article'
pg_restore: [archiver (db)] could not execute query: ERROR:  Relation 
'synd_article' already exists


I don't understand what can be this error, i just want to restore my 
database as the same it was a few hours ago.

thank you for your help,

pascal.
