-------------------------------------------------------------------
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}

> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.30.0
> Reporter: Roman Churganov
> Priority: Blocker
>
> 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}
