Bad macro in pg_wchar.h?

In src/include/mb/pg_wchar.h we have:

#define PG_ENCODING_BE_LAST PG_ISO_8859_8
#define PG_ENCODING_FE_LAST PG_WIN1256

but the last client encoding in the enum list is actually PG_GB18030 and
it seems that

#define PG_ENCODING_IS_CLIEN_ONLY(_enc) \
(((_enc) > PG_ENCODING_BE_LAST && (_enc) <= PG_ENCODING_FE_LAST)

can never be true.

I think the define should read
#define PG_ENCODING_FE_LAST PG_GB18030

On the other hand, perhaps no-one cares, because
PG_ENCODING_IS_CLIEN_ONLY is never used.
