-------------------------------------------------------------------

function MIN() actually will be pushed to sub-query, but if some unsupported fun taken, with a simpler query it makes sub-query without aggregate:
{code:sql}
SELECT "DEPTNO", ', ' AS "$f1" FROM "EMP" 
{code}

>          Components: core
>    Affects Versions: 1.30.0

> Execute query like: 
> {code:sql}
>   select C11, LISTAGG( distinct C12, ', ' )  
>          from FOO  
>          group by C11
> {code}
> In case of JDBC driver doesn't support LISTAGG function (Postresql),  JDBC adapter creates subquery:
> {code:sql}
> SELECT "C11", "C12", ', ' AS "$f2"
>      FROM "FOO"
>      GROUP BY "C11", "C12", ', ' 
> {code}
> which cannot be executed on Postresql and gives error  :
> {noformat}
>    [42601] ERROR: non-integer constant in GROUP BY
> {noformat}
