postgres=# insert into test15 values (to_tsvector('jiebacfg', 'hello china, i''m digoal')), (to_tsvector('jiebacfg', 'hello world, i''m postgresql')), (to_tsvector('jiebacfg', 'how are you, i''m digoal'));
INSERT 0 3
postgres=# select * from test15;

 ' ':2,5,9 'hello':1 'm':8 'postgresql':10 'world':3
 ' ':2,4,7,11 'digoal':12 'm':10
(3 rows)

postgres=# create index idx_test15 on test15 using rum(c1 rum_tsvector_ops);
CREATE INDEX
postgres=# select *,c1 <=> to_tsquery('hello') from test15;
                         c1                          | ?column?

return duplicate tuples;
