Thanks for the guideline on ASJ, Roberto.
Altho I couldn't seem to find a direct link from
www.arsdigita.com/asj, after doing a site-wide search, I found the appropriate doc which talks about internationalization. Here is the link for those who wanna check it out:
Building a Multilingual Web Service Using the ACS
Also, from
PostgreSQL: Introduction and Concepts, there is a short section which mentions
Internationalization support in PostgreSQL.
Sincerely,
