+# Queries of the form: |
+# |
+# SELECT group_concat(x) FROM (SELECT * FROM table ORDER BY 1); |
+# |
+# The ORDER BY would be dropped by the query flattener. This used |
+# to not matter because aggregate functions sum(), min(), max(), avg(), |
+# and so forth give the same result regardless of the order of inputs. |
+# But with the addition of the group_concat() function, suddenly the |
+# order does matter. |
