Problem with the tag 'motorboat'

[F3L1X79]

Hello,
It looks like the query:
CREATE INDEX idx_planet_osm_line_motorboat_waterway ON planet_osm_line USING btree(waterway,(tags->'motorboat'),(tags->'CEMT')) WHERE waterway IS NOT NULL AND (tags ? 'motorboat' or tags ? 'CEMT');
is not working anymore with the latest OSM datas, got error:
ERROR: column "motorboat" does not exist

Any clue?
