    Encoding PG_UHC is code page 949.
    
    This fixes presentation of non-ASCII messages to the Windows event log
    and console in rare cases involving Korean locale.  Processes like the
    postmaster and checkpointer, but not processes attached to databases,
    were affected.  Back-patch to 9.4, where MessageEncoding was introduced.
    The problem exists in all supported versions, but this change has no
    effect in the absence of the code recognizing PG_UHC MessageEncoding.
    
    Noticed while investigating bug #13427 from Dmitri Bourlatchkov.
