ALTER AGGREGATE cannot change COMBINEFUNC or PARALLEL. My current patch
updates the system catalogs directly, which should be safe in this case, but
is this an acceptable solution?

I'd rather extend see us ALTER AGGREGATE to do this.

Wouldn't that prevent this from going into 9.6? I do not think changing ALTER AGGREGATE is 9.6 materials.
