German_stem is part of distribution. I am thinking so result of stems
are usable because the reports about slow speed are not often.
There are not exists Czech stem, so we have to use a ispell. I wrote a
patch that stores loaded dictionary in shared memory. You can find
source code in archive pg_hacker mailing list. But it isn't well
tested and it is just prototype - not accepted to pg. You can test it.
Sometimes people use a >>simple<< configuration here. It isn't best
but it is fast.
