PostgreSQL can handle Big5 since 6.5. Create a database with the encoding
EUC_TW, and set the client side encoding to BIG5. For example, set
PGCLIENTENCODING envrionment variable to BIG5 before starting psql or
any libpq based clients. For 7.0 or greater version of PostgreSQL, you
could also use \encoding command in psql.
