show lc_collate;

Is it that this is handled by tsearch2? Or I need to do the locale to

See http://www.postgresql.org/docs/8.3/interactive/indexes-opclass.html. It tells you how to create an index that like might use in non-C locales.

As a side note, the ^ in the string above has no special meaning for like.
