pgsql: Fix machine-dependent crash in sqlchar_to_unicode(). - Mailing list pgsql-committers

Log Message:
-----------
Fix machine-dependent crash in sqlchar_to_unicode().  Get rid of
bletcherous and unsafe manipulation of global encoding setting.
Clean up libxml reporting mechanism a bit (it still looks like a
dangling-pointer crash waiting to happen, though, not to mention
being far less than sane from a localization standpoint).
