pg_updatedicts - build PostgreSQL dictionaries from myspell/hunspell ones
pg_updatedicts makes dictionaries and affix files from installed myspell
and hunspell dictionary packages available to PostgreSQL for usage with tsearch
and word stem support. In particular, it takes all *.dic and *.aff files
from /usr/share/myspell/dicts/, converts them to UTF-8, puts them into
/var/cache/postgresql/dicts/ with *.dict and *.affix suffixes, and
symlinks them into /usr/share/postgresql/>version/tsearch_data/, where
PostgreSQL looks for them.
Through postgresql-common's dpkg trigger, this program is automatically run
whenever a myspell or hunspell dictionary package is installed or upgraded.
