Well, that would really work. We have the same problem also in the case we
don't have a subquery. Eg. from Postgres:
```
mgaido=# select 1 from (select (1, 'a') as col1) tab1 where col1 in ((1,
'a'));
ERROR: could not identify an equality operator for type unknown
mgaido=# select 1 from (select (1, 'a') as col1) tab1 where (1, 'a') in
((1, 'a'));
?column?
----------
1
(1 row)
```
