psql: Fall back to English for unsafe hidden query labels. This completes the project begun in commit 294d2196c of making commit 41d69e6dc's hidden query labels safe against unexpected encoding-related failures. At that point we were still uncertain exactly what rule to use to decide that a translated label is safe. The rule adopted here is: translate the label only when the client and server encodings match and the translated bytes pass the same encoding verification check the server will apply. This is enough to ensure that no error will be thrown, and it avoids the difficult task of identifying what encoding gettext() thinks it's using.
