0af16ab2c2 Make sure that GROUP BY terms select input column names in preference to 
output column names, in compliance with the SQL standard.

e35463b312 Bare identifiers in ORDER BY clauses bind more tightly to output column name, 
but identifiers in expressions bind more tightly to input column names.
This is a compromise between SQL92 and SQL99 behavior and is what
PostgreSQL and MS-SQL do.  Ticket [f617ea3125e9c].
