And join opertator for tsqueries is the same :
select 'fat'::tsquery *** 'cat'; ?
Single '*' ? That's close to regex, any number of tokens. And it saves rules
about duplicating character.
select 'fat'::tsquery ** 'cat';
select 'fat * cat'::tsquery;
select 'fat * [3] cat'::tsqyery; -- for non-default distance.
