The correct solution is probably we will have multiple locales in
single database cluster. We should set the locale after deciding
the encoding nowm, but I think the current implementation is wrong
because locale depends on encoding, but the opposite is not true.
(locale = 'language_country.*encoding*')

If you will go to the multiple text-search support, we'd better to
get done the locale issue first. It might affect your new parser.
