Last time I just extracted interesting parts of queries from tpc-h (to
be able to look at bitmapscans/hash-aggs in isolation) and ran tpc-h as
a whole. During development I also tried to come up with adverse cases
(e.g. huge bitmapscans, with very low work_mem). I don't really have a
lot better ideas than that.
