Locale support

Hi!

I've compiled Postgresql-7.2 with locale, recode and multibyte support.
I read the documentation about "locale" support, and I understand what
this is ussefully when I need the system/database messages in a
determinated language. Is correct this?
I need to support the japanish language, for example, and I need when a
make a query to database, with PHP, the results are in japanish.
Can the database make this directly, or I need to make this via php
programation, making a php connection with postgres with the appropiate
arguments?

Thank you very much.
