Given the soft-input-error feature, we can reduce these functions to be just thin wrappers around a soft-error call of the corresponding datatype input function. This means less code and more certainty that the to_reg* functions match the normal input behavior. Notably, it also means that they will accept numeric OID input, which they didn't before. It's not clear to me if that omission had more than laziness behind it, but it doesn't seem like something we need to work hard to preserve.
