Log message:
    Aggregates can be polymorphic, using polymorphic implementation functions.
    It also works to create a non-polymorphic aggregate from polymorphic
    functions, should you want to do that.  Regression test added, docs still
    lacking.  By Joe Conway, with some kibitzing from Tom Lane.
