Looking a little more:

* No tests exercise non-const offsets

* No tests for default clauses with IGNORE NULLS

* The use of bitmapsets is quite ugly. It would be nice if the API would
grow the BMS within the memory context in which it was allocated, but I
don't even see that the BMS is necessary. Why not just allocate a
fixed-size array of bits, and forget the BMS?

* Is there a reason you're leaving out first_value/last_value/nth_value?
I think they could be supported without a lot of extra work.
