Make UNKNOWN into an actual pseudo-type. Previously, type "unknown" was labeled as a base type in pg_type, which perhaps had some sense to it because you were allowed to create tables with unknown-type columns. But now that we don't allow that, it makes more sense to label it a pseudo-type. This has the additional effects of forbidding use of "unknown" as a domain base type, cast source or target type, PL function argument or result type, or plpgsql local variable type; all of which seem like good holes to plug.
