I woud think that using the crosstab functions in tablefunc would solve the problem without needing a complete change of structure. I've built crosstabs over a whole lot more than 54K rows in far, far less time (and resulting in more than 35 columns, too) than the 11 seconds that was quoted here, without feeling the need to deal with hstore or similar. In fact, wouldn't hstore actually make it more difficult to build a crosstab query than the schema that he has in place now?
