> Before digging into the problem, could you share your impression on whether PostgreSQL can support SJIS?  Would it be hopeless?  Can't we find any direction to go?  Can I find relevant source code by searching specific words like "ASCII", "HIGH_BIT", "\\" etc?

For starters, you could grep "multibyte".
