> In 10.2, this query gives the following error message:
> ij> SELECT i FROM t GROUP BY i ORDER BY j;
> ERROR 42Y30: The SELECT list of a grouped query contains at least one invalid expression. If a SELECT list has a GROUP BY, the list may only contain valid grouping expressions and valid aggregate expressions.  
> This is misleading since there is no invalid expression in the SELECT
> list.  It is the ORDER BY clause that is wrong.  
> I have marked this as an regression since the error message in 10.1 is
> more helpful (but still not correct):
> ij> SELECT i FROM t GROUP BY i ORDER BY j;
> ERROR 42Y36: Column reference 'J' is invalid.  For a SELECT list with a GROUP BY, the list may only contain grouping columns and valid aggregate expressions.
