intellectual property represented by the database confidential. The fear may be that the users will reverse- engineer the database for their own purposes, or that these remote sites will fail to maintain

now disallowed since a numeric can be converted to a string in different ways. However, for the reverse case, INTEGER_FIELD = STRING_ARGUMENT, index scanning is allowed because the conversion is deterministic
