When I committed d0d44049d (Account for optimized MinMax aggregates during SS_finalize_plan), I didn't have a test case showing that it was fixing any reachable bug. Here is one, based on bug #18465 from Hal Takahara. Without the fix, all rows of the result show the same "min" value, because the aggregate doesn't get recalculated. Committed despite beta1 release freeze, with the concurrence of pgsql-release.
