only dictionaries use stop-words, so check dict_initoption in pg_ts_dict table:

w=# select dict_name,dict_initoption from pg_ts_dict;
      dict_name      |      dict_initoption
--------------------+---------------------------
  simple             |
  en_stem            | contrib/english.stop
  ru_stem_koi8       | contrib/russian.stop
  ru_stem_utf8       | contrib/russian.stop.utf8
  ispell_template    |
  synonym            |
  thesaurus_template |

btw, did you read tsearch2 documentation ?
