Greetings,
Although I am not an expert in this field, I carefully read the full-text search section in the document. I think the change is surprising, but yes, it is correct.
I found that your patch didn't modify the regress/excepted/tsearch.out. So I updated it and carried out the regression test. It passed. Also, I manually executed some test cases, all of which were OK.
