There was already a check on the relation OID, but not its index OID and the attributes that can be used during the syscache lookups. The two assertions added by this commit are cheap, and actually useful for developers to fasten the detection of incorrect data in a new entry added in the syscache list, as these assertions are triggered during the initial cache loading (initdb, or just backend startup), not requiring a syscache that uses the new entry. While on it, the relation OID check is switched to use OidIsValid().
