Restore option disabled for non-superuser

PgAdmin 1.12.2 on WindowsXP
postgresql 9.0 on linux

When connecting as 'postgres', 'Restore' option is available, but when 
connecting as 'testuser' (simple user, nocreatedb), even for database 
owned by testuser, restore options are greyed out.

I think they should not be disabled, in many scenarios db may be 
restored by non-superuser.
