The error messages says all. PostgreSQL accepted 'データベース'
encoded in UTF-8 then tried to convert to EUC_KR but failed, because
EUC_KR does not accept languages other than Korean (and ASCII). What
else did you expect?

0xa0 is definitely not part of EUC_KR. That's why PostgreSQL throws an
error. I gues you are using UHC (Unified Hangul Code), rather than
EUC_KR. They are different encodings. You should do either:
1) Make sure that your termical encoding is EUC_KR.
2) set client_encoding = 'uhc';

This is because the same reason above.
