error on pg_restore

I created a user pguser and gave it all the privileges on database RIC.

CREATE USER pguser WITH PASSWORD 'xyz123!';
GRANT ALL PRIVILEGES ON DATABASE "RIC" to pguser;

The database RIC was created by user postgres earlier.

Now, when I run the pg_restore I get an error:

xzcat "postgres-071215200001-database" | PGPASSWORD=xyz123!
/opt/PostgreSQL/9.4/bin/pg_restore -h onxv0097 -U pguser -d RIC -c -p 5432
