Snowball has made a release! With a tag!
I have prepared a patch to update PostgreSQL's copy. (not attached
here, 566230 bytes, but see
https://github.com/petere/postgresql/commit/52a6133b58c77ada4210a96e5155cbe4da5e5583)
Since we last updated our copy from their commit date 2019-06-24 and the
release is from 2019-10-02, the changes are pretty small and mostly
reformatting. But there are three new stemmers: Basque, Catalan, Hindi.
I think some consideration could be given for including this into PG13.
Otherwise, I'll park it for PG14.
