OK, I updated the TODO text with:
PostgreSQL 9.1 will allow result columns that are not referenced by
GROUP BY if a primary key for the same table is referenced in GROUP BY.
Hopefully we can reevaluate this for 9.2. This is an unusual case
because it is a not-wanted TODO entry (which always come across as
harsh), and we didn't complete it (so we can't mark it as done).
