You really should define what you mean by "works" in a question like this.

However, I think what you are unhappy about is that the interpretation of that to_tsquery input has changed.  In v13:

regression=# select to_tsquery('simple', 'real,impact');
    to_tsquery     
-------------------
 'real' & 'impact'
(1 row)

In v14 and later:

regression=# select to_tsquery('simple', 'real,impact');
     to_tsquery      
---------------------
 'real' <-> 'impact'
(1 row)

The v14 release notes mention that there were incompatible changes in this area, although they don't cite this specific case.  But anyway, if the behavior you want is & then I'd suggest writing &, rather than assuming that some other punctuation will behave the same.  Or you could switch to plainto_tsquery(), which disregards the punctuation altogether.
