Can pgsql fts do stemming or more complex lemmatisation for languages other than English? Or ranking of results based on Okapi BM25 or similar? I was looking into this about two years ago and those were the features in favor of Lucene (basis of ES and Solr).

Pgsql can do stemming and everything it can do in English also in several dozen languages, including German, French, Spanish, and any for which you install dictionaries. It’s quite useful

As far as I am aware, it does not support BM25. See pilif's comment about multiple language support.
