I think the OP meant to write: "If the expression is an aggregate expression, it is evaluated across all rows in the group. Otherwise, it is evaluated against a single arbitrarily chosen row from within the group. "
Is there a way I could programmatically determine that a query is going to use an arbitrarily chosen row from within the group at query prepare time?
