Ichiran Postgres database dump (May 2021 update)

Apropos of nothing, another Ichiran update!

A possibly breaking change is the support for classical -す causative form (i.e. 言わす vs 言わせる).

Create a new database from this dump using the following commands:

createdb -E 'UTF8' -l 'ja_JP.utf8' -T template0 <database_name>
pg_restore -C -d <database_name> ichiran-170521.pgdump

Note: run (ichiran/mnt:add-errata) after configuring your ichiran to use this database to get the latest database fixes.
