previous rule was: duplicate operation character to join tsqueries.
Ellipsis is forbidden to use as operator name:
# create operator ... (procedure = 'int2and');
ERROR: syntax error at or near ".."
LINE 1: create operator ... (procedure = 'int2and');
What is your suggestion for joining operator name?

Yes, agree for omission. But for reason above its'n a good name although I don't
have a strong objections.

may be <=>? it isn't used anywhere yet.

select 'fat'::tsquery <=> 'cat';
select 'fat <=> cat'::tsquery;
select 'fat <3> cat'::tsqyery; -- for non-default distance.
