Обсуждение: pgsql: Fix up some oversights in psql's Unicode-escape support.

Fix up some oversights in psql's Unicode-escape support.

Original patch failed to include new exclusive states in a switch that
needed to include them; and also was guilty of very fuzzy thinking
about how to handle error cases.  Per bug #5729 from Alan Choi.
