Restore and Backup PG8.4 tp 9.4

[Mohamed MANSOUR <med.mnsour@xxxxxxxxx>]

hi , 

i have been restoring my old server pg8.4 with this command in Ubuntu 15.04 

pg_dump -i -h localhost -p 5432 -U postgres -F c -b -v -f  "10.70.0.61.backup" myDb

i try to import this backup in my new server pg 9.4 with this command 

pg_restore -i -h localhost -p 5432 -U postgres -d myDb -v "10.70.0.61.backup"

the backup worked fine but in restoring i get this error ! 

pg_restore: connecting to database for restore

pg_restore: [archiver (db)] connection to database "myDb" failed: FATAL:  Ident authentication failed for user "postgres"

pg_restore: *** aborted because of error

what is the problem please ?
