You want an ispell-based dictionary instead. PostgreSQL doesn't ship with real ispell dictionaries, so you have to retrieve the files yourself and install them into $SHAREDIR/tsearch_data as described in the docs for https://www.postgresql.org/docs/12/textsearch-dictionaries.html#TEXTSEARCH-ISPELL-DICTIONARY Cheers, Jeff
