RE : Restore and back up OGo database

Hello
 
I want to restore and back up OGo database with postgreSQl
 
So I manage to save database like that
$ su - postgres
$ pg_dump -boFt OGo > OGo.tar
 
the file called OGo.tar is created in /var/lib/pgsql
 
And to back up database, I execute this commands :
$ pg_restore -U OGo -d OGo OGo.tar
Errors : pg_restore: [archiver (db)] connection to database "OGo"
failed: FATAL: IDENT authentication failed for user "OGo"
 
and 
$ pg_restore -d OGo OGo.tar
Errors : pg_restore: [archiver (db)] could not reconnect to database
"OGo"
failed: FATAL: IDENT authentication failed for user "OGo"
 
I need some help ?
Some idea to resolve my problem ?
 
Sorry for my english...
